I feel terribly depressed. My Dr says sounds like ADD but I'm thinking bipolar. I was diagnosed with major depression when I was a teen. Throughout my life I have been on and off antidepressants. I'm currently taking Prozac and now added Wellbutrin XL. I can seriously check every yes there is to bipolar quizzes on how depressed I feel. I don't know what to do. I've had a lot of things happen to me in the last year that I feel may have sparked bipolar disorder or ADD (as my dr thinks). Does anyone really know how to find out what the problem is? Please help.
