One of DHs old friends is staying with us after marital breakdown. I've met him casually over the years. Now he's here I am beginning to suspect he may have ADHD. No impulse control, restless, only able to complete tasks if he's very motivated by them/constant prompting, has left undone crucial things in his life that are now having big consequences that were foreseeable, no ability to safety net himself...
And he is sad, and lost, and kicking himself for what he has/hasn't done, and full of self loathing... and then goes off on the same road again.
Is there anything I can do to help him focus, manage, stop the impulses? I have no close personal experience with ADHD.
