Welcome to our forum.
Polyamory.com is quite a bustling site, so you should find a goodly number of opportunities to engage in conversation (which has its way of growing friendships in due time). Have a look around; see what threads call to you; start new threads if you want; let us know of thoughts, questions, and/or concerns that come to mind.
I'm curious how one can lose one's outgoingness! Do people seem to be avoiding you nowadays (out there in "meatspace")? It sounds like you're casually seeing someone so that's a start, right?
I'm curious (being a curious type) about the hand problems you spoke of. Would I be prying to ask? (If so, pay the question no mind.) Some kind of chronic carpel tunnel syndrome, perhaps?
Lonesomeness is no fun and I hope our "digital society" cures some of that for you. Glad to have you with us!
Love means never having to say, "Put down that meat cleaver!"
