I Am Sometimes Antisocial

It's really hard because I I'm naturally and outgoing person. I used to love people I used to trust people until about four years ago when all the drama started.I don't know if it's my depression or if it's because I'm starting to for a walk and not like people as much. I just get irritated by people too fast. It seems like people don't have common sense and people are really cruel versus I used to think people are ..often good.. I actually hate this huge change.. I can go days without talking to people and ok. My whole life I always love to be around people and it was hard for me to I was very open with my problems. I don't know what's happening I think it's trauma.
