It sounds like you need some friends in the maker space or something similar where tinkering in something temporary is normal. I'd say you're among friends in the HN space where tinkerers are more common!
Keep working on your trauma. Don't however think that your healing is a requirement to have friends, love, etc. We are all broken and hurt. We are broken together.
I've tried a couple times, but the interest in making physical things cycles through just like any other interest. Then it gets replaced by something like neurobiology or anthropology and I don't want to make things for awhile.
It seems like I really enjoy the beginnings of things, like if we run Pareto ratios twice, I like the 4% of the learning that gets me 64% of the understanding. And then it's enough and I'm done. It's enough to ask questions of the interesting people without sounding like a total n00b.
In the time it would take to master one thing, I become "barely proficient" in 25, but it's hard to build anything meaningful, including human connections, operating like that.
I know healing isn't a requirement to deserve the friendship of others. But if I keep operating like this because of it, it's definitely an impediment to building those friendships.
Ya, your situation is rough. Made many fold harder by today's isolating culture and technology.
Have you found any artists or creators to hang with?
Especially these days, artists have to be very tech savvy. I've always enjoyed helping others with their projects. (I possess the artistic talent of sea kelp rotting in the sun.)
In my experience, makerspaces have dabblers, not doers.
