Where it has led

I figured out today that I Am ADHD. I am 63' a widower. My wife.committed suicide in 1999' when our children were 16 and 12. They both have college degrees and jobs. I retired at 59 Iin 2007, had a stroke in 2009', sustained an injury in feb. 2009 and have chronic pain and a visual impairment. I had $80,000 in liquid assets in 2009, and nothing now. I can't drive, can't buy a date,pay for a caregiver and realize I thrived under the demands of single parenthood and crumbled in retirement. Is this how we inattentive adhds end up? My therPist doesn't think I"m ADHD. I think constantly of my losses, have no motivation and anticipate no improvements. What can I do?
