This makes me quite sad. I have two friends transitioning rn and they have partners and a somewhat supportive families (and the members who aren't they dropped a few years ago). But to feel like you are all alone is :(!
I'm terrible with making friends or anything social, really, I'm anxious af (terrible adolescent and teen years, so I distanced myself from all but a handful of close people). The ones I have I like very much, but I don't really understand the process of making new friends, others just sort of bring me into their circles and I'm like 'oh ok'. But if you want to chat about whatever, maybe play some games, you can pm me. This goes for anyone else reading this and feeling similar. I'm super awkward but if I can maybe make someone's day or be someone to just talk to, I'll break out of my shell and try to be supportive. I've been trying to push myself socially anyway, not be so scared of interacting with others, so I'd be mutually beneficial. Plus, yay friend maybe?
Regardless, I hope you find some people who support you. internet hug!
