That's another problem. I've been friendless since my teen years. (Isolated homeschooling + living with panaroma paranoid parents in early 20s and being financially dependent to not move out + difficult to make friends in late 20s).
Well, I made friends in college, but I didn't really connect to those people too deeply or liked them much (it was a competitive art school), so they all faded away after graduation. Past 1.5 years has been moving out and healing and doing lots of things to meet people, but it's hard to meet people who click with you and are consistent and genuine, etc.
I've just met those people (group of 5 people, including me) the past few months, consistently hanging out with them (parties, drinks, playing sports together, hanging out at each other's places). So, finally, it's happened, but it's still recent in the friendship.
