You know that better than I! But it sounds like you've put some thought into it. I'm a late diagnoser so went through most of my life blaming myself because I didn't know I had a condition to blame. At this point, I couldn't even imagine not being me. If I'm autistic then that's because someone has defined this thing they named autism and set some almost arbitrary criteria to decide who is and who isn't. In some ways, I'm happier just being the weirdo!
I've suffered depression most of my life (jeez! I can hear violins playing!) which hasn't been fun, though not the worst of depressions, but I still crave to see what will happen next, and have never wanted to end it, just end the pain of it (though that can be a route to substance misuse, not very helpful in the long run).
Every time I came out of a depressive state, it always reminded me there are things worth experiencing, and thinking, about and however bad it may sometimes seem, at some point it does get better.
