I never had friends, to start. I can socialize, though. I avoided people as a kid into adulthood, because I saw everyone as a threat. I couldn't trust anyone because of the intense abuse I was facing.
The problem is that people think I'm hiding something because I don't have any friends. Like I'm up to no good? It'll come up eventually. Being 31 now, it seems that I'll have to get used to being alone.
