Sorry that you're having such a rough time!! It's not true that only a gynecologist can prescribe birth control -- a GP can also prescribe BC. Who cares if she can or not, though, obviously you don't want to go back to see her!
I find it hilarious that she WON'T prescribe you ADs for IBS, because when I was misdiagnosed w/ IBS for so long, everyone kept pushing ADs at me. I did try Elavil at the suggestion of the first GI, but it did nothing for me -- which, since I have endometriosis and not IBS, makes sense.
When you do see a doctor, don't just say you're depressed to get them to refill the script -- tell them the whole story, including your reaction when you went off of it, and your belief that you do need the AD for both your IBS and anxiety issues.
Although, just want to say that you did go off it way too quickly, so your symptoms are probably withdrawal and most likely not what you'll be all of the time when you're off it. Obviously if it's helping and if a REAL doctor doesn't see any reason to go off, though, then no reason to stop taking it.
Good luck ...
