How do I, yknow, make friends..?

I've been playing on PT for about six months now, on and off. And I don't know why I keep coming back. Nothing interesting ever happens.

Most of my skins are of OCs, so I don't normally get involved in roleplay.

I'm too afraid to start a conversation.

I am not in many fandoms, and the ones that I'm in are relatively small.

I'm not good enough at skinmaking to talk to people about that.

I'm not in any of the "armies" or "species."

I don't know what to do. I'm considering putting it down for good, leaving it behind, because it doesn't really contribute anything to me. I'm not making friends, I'm not having fun. I'm just sitting there wasting time.
