I know this may sound odd, but have you had a medical work-up for these problems? It is possible that not all of it is caused by your anxiety and depression. I don't know you, but I'm wondering if something else might be going on, as well.

I would recommend you go to your primary care doctor and ask for a full physical, blood tests to check your hormone levels (ie. thyroid, etc), and maybe even a test to see if your swallowing is normal or if something is constricting your esophagus. Don't let your doctor dismiss you and just say to go back to your psychiatrist. Tell him that the psychiatric drugs don't work and you are concerned something else may be going on. Tell him all of your symptoms and hold nothing back. He'll need the full picture.

If everything comes out normal, talk to your psychiatrist about other treatment possibilities. Maybe biofeedback would help you recognize when your body is responding to the anxiety and help you learn to relax your throat.

Good luck with everything. Please write back and tell us how everything works out.
