My son has ADHD and I never knew what it meant but this year I made him get coaching for it and I made him get meds. He was living at home for free rent and the condition of staying was to address this. My experience is that getting treatment for this condition helped him a lot. The coach really helped, the meds really helped. He is full of zest for the work that lies ahead. He's off on his own now and while I think he'll have stumbles it's basically very positive.
One thing about ADHD coaching. The coach is a consistent person who helps frame a positive attitude with agency and skills and this takes you away from negative self talk. It's good. I think ADHD folks need this positive support.
