Are you a diabetic?

The drugs you are taking indicate some serious conditions...did you run this by your doctor? I'm afraid you may be putting yourself in danger by stopping them; what are you taking them for?

As for the stringy stuff, it does sound like candida which can be caused by long-term Antibiotics . You will have die-off, but this seems like more going on.

Regarding the depression, try natural sources of seratonin like 5-htp or l-tryptophan from health stores to transition from the wellbutrin. It's just as effective as synthetic anti-depressants without the side effects...some say well-butrin can cause weight gain so that may be where THAT comes from. And the naturals will definitely help your mental state NOW.

But please contact your dr about your suddenly stopping those serious drugs; I'm generally not a big believer in drugs but these indicate some serious issues and stopping them suddenly may be part of the problem?
