Despite being clinically different disorders, anxiety and depression can appear quite similar in their symptoms. Naturally, this can lead to confusion about how to tell them apart and if a person can have both at the same time. So, what is the difference between anxiety and depression? And is it possible to have both at the same time? To help you answer these questions, here's an overview of the two conditions and what each one's symptoms are.

What is Anxiety?

Most people experience feelings of anxiety at some point in their lives. The occasional panicked breathing, chest-thumping, or feelings of worry are natural. But when they last for extended periods or happen consistently, it may signal an anxiety disorder.


Essentially, a person with an anxiety disorder experiences a pattern of constant and excessive worry that's hard to control and often affects their daily lives. There are many types of anxiety disorders, but the most common is generalized anxiety disorder (GAD). Others include social anxiety disorder, panic disorder, phobias such as claustrophobia and agoraphobia, and separation anxiety.

What is Depression?

Depression is a complex mood disorder that affects more than 264 million people in the world. Depression causes a person to feel persistently sad, hopeless, or unmotivated for weeks or months. Depression is different from normal mood swings, occasional feelings of sadness, or responses to loss or trauma. Its symptoms are lasting and can be severe enough to affect your personal, work, and family life. There are many different types of depression, with the most common being major depressive disorder (MDD).

What Do Anxiety and Depression Look Like?

What is the difference between anxiety and depression, exactly? Identifying the psychological and physical symptoms of the two conditions can help answer this.

Phycological Symptoms

  • Anxiety: The psychological symptoms of anxiety are constant worrying, feelings of extreme anxiousness, feelings of helplessness, irritability, restlessness, difficulty concentrating, and feeling on edge.
  • Depression: With depression, psychological symptoms include continuous sadness, loss of motivation, loss of interest in hobbies/activities, thoughts of self-harm, irritability, feelings of anxiousness or helplessness, feelings of guilt or worthlessness, difficulty concentrating or making decisions, and continuous empty moods.

Physical Symptoms

  • Anxiety: The physical symptoms of anxiety include fatigue, insomnia, muscle aches and tension, heart palpitations, dizziness, shortness of breath, excessive sweating, stomach aches, dry mouth, and headaches.
  • Depression: Some of the physical symptoms of depression are fatigue, insomnia, oversleeping, unexplained pains, constipation, changes in appetite, changes in weight, and speaking or moving slower than usual.

Do I Have Anxiety and Depression?

It is possible to have both of these conditions. Although anxiety and depression are distinct from one another, they are often co-morbid. This means that many people with anxiety also have depression (and vice versa).


In fact, studies reveal that approximately 67 percent of people with lifetime GAD also report having MDD. And 20 percent of people with MDD report having GAD. Sometimes, when a person has both anxiety and depression, they co-occur simultaneously. In other cases, one is caused or triggered by the other. It's important to remember, though, that only a trained mental health professional can diagnose you with any (or both) of these conditions.

What's Next?

Anxiety and depression symptoms can interfere with your routine and negatively impact your life. Fortunately, they are very treatable. If you suspect you have depression and/or anxiety (or you already have a diagnosis), you should seek appropriate treatment. A mental health professional can give you an accurate diagnosis and help you decide which available treatment option is best for you.


If you have tried medication and talk therapy and found limited success, you can consider non-drug treatments, such as transcranial magnetic stimulation (TMS). TMS is a proven treatment for people with MDD that does not respond to medication. And if you have co-morbid anxiety symptoms, treating MDD can sometimes help you manage those symptoms as well.

We’ve all heard the common health-related misconceptions or myths-- chocolate causes acne, carrots will improve your night vision, and cracking your knuckles gives you arthritis. Subscribing to these particular myths is relatively harmless, but other health-related misconceptions can have far more serious consequences. This is the case for depression—the myths surrounding it can prevent people from getting the help they need.

Starting any medical treatment for the first time can leave you with questions, especially if you’re looking forward to the benefits it may bring. It’s no different when you’re preparing for your nasal esketamine treatment. Your previous mental health treatments may have consisted solely of taking antidepressants at home or visiting a therapist’s office for cognitive behavioral therapy (CBT), so nasal esketamine is probably a new treatment experience for you. If you're wondering what it's like to start nasal esketamine and get ready for your first session, keep reading. Getting Started with the Nasal Esketamine Treatment As with any new treatment, you’ll first talk to your primary care provider or psychiatrist about whether nasal esketamine is a good fit for you. Alternatively, you can schedule your esketamine nasal spray consultation with a treatment center (such as Greenbrook) that has certification by the FDA’s Risk Evaluation and Mitigation Strategy (REMS). At Greenbrook's REMS-certified nasal esketamine treatment centers, our Greenbrook-affiliated psychiatrists and psychiatric nurse practitioners will review your medical history and also conduct our own assessment to help determine whether nasal esketamine treatment is right for you. Certain conditions, including blood vessel disease and a history of psychosis, may make treatment a risk for you. Make sure you discuss all previous and present conditions with your doctor or nasal esketamine provider before beginning treatment. If the medication is deemed a good fit, you’ll receive your prescription from the Greenbrook-affiliated provider. Your Greenbrook Care Team will put together a personalized care plan for the weeks and months to follow. Keep in mind that you will need to take a standard (oral) antidepressant along with your nasal esketamine treatment. There are two important regulations to note when it comes to preparing for treatment: Each treatment is followed by a mandatory two-hour observation period. This means you will need to plan to stay at the center for at least two hours following your self-administration of the esketamine nasal spray. You cannot drive during the rest of the day after treatment and must arrange for transportation. These regulations are mandatory. It may be helpful to sit down and plan out several weeks’ worth of transportation once you know your treatment schedule. In addition, if you’re wondering what to bring for the treatment, we recommend entertainment such as an audiobook or playlist of favorite songs and a pair of headphones. You may want them during the two-hour observation period. What to Expect During Nasal Esketamine Treatment On the day of treatment, you’ll need to stop eating any food two hours before your appointment and stop drinking all fluids 30 minutes before you come in. Your Greenbrook Care Team will confirm that you are prepared for the two-hour observation period and that you have a ride home. You’ll get the opportunity to practice using a “trainer sprayer” that mimics the real nasal esketamine sprayer but does not release any medication. The Care Team will encourage you to use the restroom and set up your preferred environment in your private treatment bay or room. Some patients like reduced lighting, for example, while others don’t request light adjustments. You’ll complete a depression scale before each treatment session. Your Greenbrook provider will confirm that the dose kit is yours, show you how to administer it, and then hand it to you. Each sprayer contained 28mg of Spravato esketamine nasal spray. Patients usually start with two sprayers (56mg) and soon increase to 84mg (three sprayers) per treatment. But, your dosage maybe vary. Should you be left with a metallic taste by the spray, the Care Team will offer suckers to help make the flavor dissipate. After your dose, you’ll be encouraged to lie back in your comfortable recliner. While most patients enjoy a quiet setting, Greenbrook is prepared to accommodate patients with a more animated reaction to the medication. You may feel sleepy, dizzy, mildly dissociated, and/or nauseated during treatment. Greenbrook's Care Team is readily available if you need assistance. How to Prepare for after your Nasal Esketamine Treatment  Most side effects begin to wane in the second hour of observation, but if you’re wondering, “Is it safe to drive immediately after nasal esketamine treatment?” the answer is a resounding no. In addition to the mandatory ride home, you will need to block off time to rest and let side effects fully dissipate. This extended rest period is especially important in the first weeks of treatment when you’ll have treatment twice a week. Do not drive or operate machinery of any kind until the day after treatment. Just take it easy, relax, and take care of yourself. If you’re unsure what activities you can do or should avoid during this time, talk to your Care Team for more information. While side effects tend to dissipate completely after a good night’s sleep, many nasal esketamine patients begin feeling relief from depression symptoms within hours of their treatment. Other Tips in Preparing for Your Nasal Esketamine Treatment At Greenbrook, we make every effort to schedule your treatment in the afternoons or whenever it is most convenient for you. We encourage you to see each treatment session as an opportunity to relax and take care of your mental health. If you have any questions or concerns, talk to your doctor or the Greenbrook Care Team. At Greenbrook, we’ll help you feel at ease when preparing for each treatment session. Schedule A Free Consultation To get started with nasal esketamine, schedule your free consultation today.
