Ask your doc for a referral to a psychiatrist, who can best assess you, offer you an official diagnosis (there are many different anxiety disorders), and start discussing treatment options
with you. Antidepressants (ie
Zoloft, Prozac, Lexapro) may be very helpful for you, and also therapy. Therapy will help you learn coping mechanisms to help you deal with the anxiety. Stay away from any and all substances, including alcohol. They will all trigger anxiety.
