I don’t know what to do

I (25F) don’t know how much more I can take. I have severe ADHD and depression, and take medication for both. Nothing works. I have spurts of happiness that barely last a few days. I constantly fuck up. I never learn from my mistakes. I’m not growing up like I should be. I can’t find a job. I haven’t finished college. I can’t keep friendships. It’s been bad, but never this had. It’s almost like I’ve accepted that nothing will change. The idea of falling asleep and never waking up seems so peaceful. I want to be done.
