Is it normal not to care about your friends, uncle, cousins or anyone? Like, you have friends, but you couldn’t care less about them and don’t value them. If they have kids, you don’t care about their well-being either. Basically could not give less of a fuck about anyone. You don’t care about your friends or family members at all. If they are sick, you don’t care; if they die, you don’t care. Is this normal?
Op sounds like they have some trauma they are working thru. They don’t sound violent tho. I hope they get some help
ADHD people work well in groups for the reason you described. Nobody has brilliant ideas all the time. A few bright flashes is all you can ask for.
