It's a personal decision. I haven't gotten a diagnosis because I've been able to hold a job for many years, and I'm married, so I'm mostly fine. But I have spent my life avoiding most human contact, precisely because I know I'm incompatible with them, and people often want to know why I never leave the house.

I don't think there is any treatment. I think it's just a set of skills that you learn in case you want to try to pursue activities that most neurotypicals take for granted. It seems like a lot of work to me, and maybe it would be easier to just let things be, as you're saying.

I know what my limitations are and I can observe others doing the things that I can't do, including my own wife, and I imagine what life would be like if I could do those things too. But it mainly boils down to having FOMO, and thinking about how much work you want to go through in order to be able to do some of the things that you're having FOMO about.
