If you feel that you’re suffering from generalized anxiety disorder during this time, it’s important to talk with your doctor about symptoms and whether you need treatment. Your doctor will discuss the risks and benefits of taking medication, if that becomes necessary. Your doctor may conduct a physical examination and order blood tests to rule out other possible causes of your symptoms. A diagnosis of generalized anxiety disorder is based on both your psychological and physical symptoms.

Your symptoms must also be severe enough to impair your ability to go about your daily life, and must not be due to substance abuse or other disorders or health issues. Therapists often use an approach called cognitive behavioral therapy, or CBT, to treat generalized anxiety disorder. Your doctor might start you first on an antidepressant to help with your symptoms, and tell you that it may take four to six weeks to start feeling the effects, says Ken Duckworth, MD, the chief medical officer for NAMI and an assistant professor of psychiatry at Harvard Medical School in Boston. Your doctor may also work with you to figure out whether to up your dosage or add a second medication; often, one medication can enhance the effects of the other or mitigate its side effects.
