I have had serious problem solving skills ever since my adderall (dextroamphetamine and racemic amphetamine) overdose 1 yr ago, i am going through severe depression, but what could this be?

Depression: Please see your crisis worker or psychiatrist. It sounds like you felt bad enough to take an overdose 1 year ago and have not "felt well" since. In addition you are having difficulty with problem solving. This is unlikely to be related to your overdose. See your doctor soon and I hope you will start feeling better.

Psychological stress: Were you comatose following your adderall (dextroamphetamine and racemic amphetamine) OD? Was the OD an accident or intentional? I believe that your picture has the overarching theme of psychological stresses and pressures which are impeding your ability to concentrate and focus. This can significantly reduce problem solving skills. Continue going through counseling and cognitive behavioral therapy if that's what you're doing. If not, start

See Psychiatrist: please see Psychiatrist to evaluate if you really have ADHD or Bipolar disorder. If you are already on treatment for Bipolar disorder, you may need a dosage change or additional treatment. if you truly have ADHD, despite the OD, you will need a medication. Consider Straterra for ADHD. Hope this helps
