Don't give up on meds for ADD, there are so many more than a few years ago that really can help, and of course if taken as prescribed.
For quite awhile pdocs were misdiagnosing (and some still are) Bipolar disorder as being ADD and turns out that some are Bipolar and the meds for ADD work oppsite and wreak havoc for the patient, and just the opposite happens
If I were you I'd go for another opinion and see if you may have been misdiagnosed and were recieving improper treatment.
Also note a person can be Bipolar and also ADD, but that can be treated by a pdoc as well, so do not give up.
Stress is a huge trigger to problems for these 2 disorders as well as others. Give another try in seeking professional help, can't hurt, right?
Please take care and drop here anytime
