I'm basically in this situation but I'm very confused about your assumption that my friends have scattered and that I need to build a life from scratch.

I have plenty of friends and family around me, from the various communities I've been apart of before my current workplace, and I'm loving being able to spend more time with them (online) during my less-packed days than when I had to commute to and from an office full of people in different stages of their lives than me, hence less likely to become actual friends of mine.

I don't see why turning 22 should hit the reset on your entire social life.
