So so so much of this about. Not just disorders too.
You might read my comment as trying to claim that my disorders define me and that because I have these disorders I can afford to give up on this stuff because 'it's hopeless'. Truth is I've been trying to get past this for damn near a decade at this point and it's not nearly as easy as you make it out to be, and that's why I say that I don't have the same choice you think I do.
I didn't even know I had ADHD until a year or so ago, I'd just routinely lose the ability to do the stuff I love and I'd have to go find something else to do instead. Depression would stem from all the things I knew I loved but that I could no longer motivate myself to do. In fact I was probably even worse off before I knew about this because I thought that I was just doing something wrong, not being controlled by an invisible menace that most other people don't even know exists
I don't mean to be hostile or to impose that it can't be as easy as you're describing. I just don't think that it's right to say it's always just a choice how you react.
I have tons of completely involuntary reactions caused by primarily trauma, but I can't control them. They do things like force me literally out of consciousness with overwhelming guilt and/or sadness. That's not a choice. I didn't choose that. That's completely autonomous!`
