I can really relate. I've had a mood disorder since my teens and I've had issues with concentration (scattered and poor), distractability, oversensitivity, irritability. I never knew if any of this was related to the mood disorder (and no Dr ever questioned me about this stuff).

I told my Doc several yrs ago that as a Junior in college I had problems taking tests and got two D's and two F's that semester. My Doc asked me some other questions about my reading, etc. He carefully thought about it and prescribed some psycho-stimulants (adderall, ritalin, etc.) to improve my irritability. Recently, I've had a really good response to ritalin and it feels like concentration, mood have fallen into place.

Tell your Dr about anything that is troubling you and causing inner turmoil. Manic-depression overlaps with many other disorders and Doctors usually overlook this.
