Because of the two statements below from your post, do you think maybe you should consider leaving, instead of waiting to be left?
“I’m not allowed to discuss my condition. She says it makes me look more stupid than I already am.”
At the very least, maybe you both could seek counseling from a marriage/couples therapist with experience with ADHD. If her resentment has reached a point where she is emotionally abusing you (see the quote from your post above), maybe there’s no coming back. Couples counseling can help either way: It can help repair and rebuild, or it can help you separate respectfully with minimal damage.
Wishing you the best,
