How not just give up? There is nothing left, no viable career options, hobbies are pointless because there’s just no improvement past certain point anyway, no alleviation to the fucking constant hurt that’s AuDHD. And nobody gets it, nobody.
Any insight, other than “seek help”, would be welcome right about now.
You really need to take a step back if you are looking for reasons to live. Life is valuable and just being here enough reason to stay alive. You are valued even if you don’t think you are.
