I have a son who is 44 years, & I still help him. It has become so stressful that I’m thinking of moving out of state. He has not been able to get a degree, he is extremely absent minded, which drives me crazy. There are multiple other problems. He does not acknowledge the ADD, and won’t listen to anything. He has had multiple counselors, including one who specialized in Adult ADD (he was the worst). There is a clear family history of the disorder in male relatives. What to to? Like you, I have tried everything. The best I can advise is to be good to yourself, but do support her. The disease is devastating but is difficult to treat.
