I’m in a similar situation, it is really scary.
Not having a support network is difficult, humans are definitely supposed to live in groups and I always seem to find myself largely alone because I’m independent and busy.
My fix is rather than dating I’m setting out more time for old friends/making new ones.
I’m trying to get more involved in my community and just put down roots and get to know people. I know I won’t make friends straight away, but it seems like a good foundation for that.
I’m unsure about relationships, they always take a lot out of me and I think I’d rather have friends. But there are other advantages to a relationship!
