All I can say is I’m a single dad of 2 and am having the same problems. I work long hours too. I feel overwhelmed and like no matter what I try I can’t keep up. I don’t know what the solution is. I’ve tried prescribed amphetamines before but that created new problems. My therapist knows very little about ADHD. I’m meeting with my doctor and a psychiatrist this week to see if we can try different meds. The only other help I can think of is to try talking to others with ADHD.
