I know when I was first diagnosed, I was also very depressed. As time goes on and you educate yourself and figure out your body, it will get easier. I agree with the enemas. It's like putting an ice cube on bee sting (at least it was for me)
Diet is so tricky. For me my biggest problem was dairy. Any form, any amount. The food diary is a pain, but so worth it. Make sure you keep track in the diary how you are feeling. Some foods don't create problems till hours later.
Good luck and this is a great place for information.
