Well, I'm kinda new to learning about my ADD.

From what I've been able to find out so far, it is part and parcel of ADD/ADHD.
I read one article that explained ADD as an issue with regulation; regulation of attention, emotions, motivation, and organization. Apparently, some of the same areas of the brain affected by ADD are also involved in emotional regulation. Now this does not mean we are doomed or are slaves to our biology. But it does help to know what you are dealing with. There was also mention made of the fact that as adults, emotional regulation difficulties throughout life may mean that we have acquired faulty coping mechanisms or conditioned responses to stressors.

Having said all of that, I still need to get a handle on this because I don't handle frustration very well at all. I also have this tendency to recall all past failures when faced with a task that is difficult. It's like all those bad feelings of being a failure or of being considered stupid come rushing back. It's particularly bad when the task at hand seems so simple and easy for everyone else. I'm left wondering "what the hell is wrong with me that I can't do something so damned simple?" Just one example but such is my life.
