Cheryl,
I do think that being evaluated for ADHD is a logical step for you. In fact, I wouldn't limit it to ADHD, but would instead ask for a referral to a psychiatrist for a "thorough evaluation". Explain to your physician that you are having trouble and that you think it's time that you got some help.
Good luck to you! Let us know what you find out.
Oh, and no, I don't think you are "just nuts".
