Hi....you sound alot like me!
After my son was diagnosed with ADHD (years ago), eventually I saw the same doctor. It IS hereditary. I've been treated for it,for years. It helps. I only have ADD.........I could use the "H" part,but it was not to be,I guess.
We are "slobs",too.no matter how I try. When exAHG was around (neat-freak) things were a lot better in that regard (until his behavior got bad) but by that time the kids were older and had friends around and we had 20-25yrs plus to have more things in the house.
Hope4 you are feeling better SOON!
