Often stress is caused by unfinished tasks and over-commitment. In spite of the ADD, you ultimately are the one that has to find accommodations and solutions. Step One is to become as informed as is possible through forums such as this. The ultimate goal is to quit being so reactive to the world around us and to develop ways of working consistently toward the things that matter. By this I mean a household in which problems are solved constructively, in which ADD foibles are responded to with humor or support and in which expectations are flexible and realistic.
Paperwork is often one of the biggest problems.
Another real challenge for many with ADD comes in supervising others. It's crucial with ADD to find a job which holds your interest and passion, for as we have all experienced the positive side of ADD comes out when our interest is really engaged. That's when we tend to be focused, creative and energized. Oppositional defiant disorder is a label only used with children. It's not a side-effect of ADD, but a certain percentage of children with ADD are also very oppositional.
