Hi Bianca Rose,
I doesn't sound like Dr. Gastro is much interested in you as a patient. A whole month wait for a colonoscopy, while you're slowly bleeding away all your energy - not good!
Where are you geographically located? There might be some others on this forum who can suggest a doc.
Some diet changes might help. Have you quit caffeine (coffee, tea cola)? If not, you should. Ditto for hot peppers. A useful (but by no means comprehensive) fix for diarrhea is a low-fiber diet. People who are bleeding sometimes have to go on a liquid diet like Ensure. More long term, some people do well with the specific carbohydrate diet, but that's also not guaranteed.
Some of us are experimenting with low-dose naltrexone and getting good results. That's my current strategy, along with some supplements which can be bought over-the-counter: probiotics, MSM, vitamin A (from fish oil, not beta-carotene). Don't exceed recommended dosage of vitamin A (just one capsule a day).
You'll probably need that colonoscopy to get a clearer picture of what's going on. If things are really bad, surgery could be called for, but that's a professional judgment and none of us can diagnose you by Internet. If you need surgery and have trouble with your insurance company, I know of cheap alternatives if you're willing to travel overseas: Thailand - where I had my last surgery (see http://www.bumrungrad.com/).
