You must be doing something right if you are a senior in college. This a big accomplishment! I have many of the same characteristics that you have and I was not able to finish college. I am now 46 and I've recently gone back to school- I am 30 credits away from a BA. Anyway, as far as your education goes it sounds like you are nearly done- hang in there.

As far as your Dr- I would not start with a clean slate with a new DR. If you are unhappy with your current Dr find a new one but inform your new dr of what you have tried and what does not work. I think you will have a better chance of getting to a solution if your Dr knows what you've already been through.

Good luck to you!
