He doesn't get it, won't ever get it and worse than that he has made his mind up about you simply "not caring". He is wrong of course but it doesn't matter. Take care of yourself by getting on some effective meds and seriously consider leaving this job. It worries me that you seem to believe that trying harder or bucking up are even possible options. It's equivalent to telling a vision impaired or hearing impaired person to look or listen harder. This job and your boss is working on your self esteem. I would also consider not disclosing the ADHD in your next position. My experience has been that bosses always seem understanding initially but later become blaming and resentful in light of our continued challenges. Remember you are smart and capable Good Luck!
