Yeah we’ve talked about it on here before, I won’t bang on about it but I do think volunteering is worth considering especially as you’re not working. I get an inkling it might be the environment you’ve been trying, online socialising is often superficial/not genuine in my experience. Please don’t read that as criticism, because I think you’re a genuine person, but you’re in the wrong environment.
Anyhow, I understand how frustrating it is, I’m the kind of person who has many acquaintances but not many friends, and I agree it can be exhausting trying to make and establish friendships. Taking a break seems like a sensible option, I’m certainly in that phase myself.
