I'd rather have no legs. I could manage to live with a physical disability without too much shame or hassle, but I couldn't cope with not being to read and write (and learn, and communicate properly.) You know what they say: knowledge is power. A person without legs can get an education and do something with their life, but someone who is illiterate is doomed to work menial jobs (or resort to crime or prostituion, idk.) I think it would be akin to a mental disability, not only it would make life harder on a practical level, but it would also make you the target of hate and manipulation from others. I'm aware that physically disabled people endure hate, too, but not as much.
I keep myself busy and try to live in the moment. Of course, within limits, so I don't lose track of plans/the future. If you don't have much free time, there won't be too much time to ruminate on things like dying.
But tbh, I've never really cared about my own death anyway.
I used to be stalked a few years ago, and I started to search for anything related to privacy, stalking and such. (Things are ok now.)
I use rateyourmusic for (obviously) music and letterboxd for movies. The tags are useful if you want to find specific content you're interested in.
I'm in the same age range and no, I don't have memory problems. I think it's not normal to have memory problems at this age. As for the passord... Maybe you should've written it down somewhere.
count your calories and you can eat what you want
I've considered using a dumbphone, but it would be too inconvenient. There are certain Android apps that I need, like Signal or my bank account app.
