I think seeing a doctor is a good idea! Yes, begin with your family doctor, as sometimes these things are physically induced, and not emotionally caused at all!

If your MD is comfortable with basic psychotropic medications, then he/she will prescribe something for you to try... but will probably also refer you to a psychiatrist. I hope he/she would also refer you to a psychologist that would help with talk therapy. (Psychiatrists don't usually do the talk therapy anymore, but focus on the medications.)

In the meantime, try to do good self care... eating healthy foods (in addition to the junk stuff you like I guess?) and rest. Don't push yourself, don't try to do things you just can't do, that will only make you feel worse about yourself, imo.

DO try to get out around ppl. We being human do better around others...even if it's just sitting in the library. Or go to a lobby of a hotel or even hospital and sit and watch ppl..listen for squeaky shoes or look for clothes that do or don't fit! ANYTHING to distract yourself... computer games etc.

Take care!
