As ozzie suggested, there's a lot of great help out there for people who have ADD/ADHD -- all you have to do is to take the first step and ask for it. I think you'll find out that if you do get a good doctor who understands the extent and complexities of what you're dealing with, you will begin to feel better. If you do indeed have ADD/ADHD, a medication to specifically address that may be extremely helpful to you. Talk to your doc, get a referral for a therapist, and take it from there!

Good luck!
