It’s not easy having a child with ADHD, it’s not easy being a person with ADHD. How successfully we adapt to ADHD has to do with our attitude towards our situation. You have to accept that it’s up to you to adapt and adjust to your situation. You don’t get a free pass because you and/or your child have a brain that wasn’t designed for our current society. You can get accommodations, but those are only slight adjustemnts. They don’t guarantee that you’ll pass the course or get the promotion. Your attitude is all important in your  and your child’s adaptation. Again resilience is everything. You have to look at your situation as another case in which you have to do the best you can.
