What is good for bad anxiety

Apart from many sessions with an excellent therapist, a prescription for Xanax might help.  See a physician and sign up for some talk therapy.

Do physical activity on regular basis. It is very effective in any type of anxiety..

Drugs are never the answer. Deep breathing, good diet, exercise. Anxiety is part of our modern world. 

If your anxiety is really bad, you should speak with a mental health professional. You might need someone to talk to &/or medication.

You can also help yourself deal with your anxiety by doing aerobic activities such as walking, running, or swimming. You can meditate or do progressive relaxation exercises. Yoga and deep breathing can also be very helpful.
