Is this an anxiety disorder?

I have a current problem that I've realized has started to bother me more, since I'm not working. I've had more free time then I usually do, and I've been rethinking things that happened in the past. I realize if I keep busy, that this won't be a problem. Though one thing that I do is when I see- a person, a location/store, a certain word, it can remind of something that happened. I try to avoid these things so I don't have to be reminded of the event. In high school, I was teased for being shy, and not having clear skin. It's a part of my life that I wish was different. I haven't thought about it until recently. Even now, If I'm somewhere, and something negative happens, or someone says something to me that is negative, I've noticed that I want to avoid the place so I don't want to re-think the situation.

What is the proper term for someone who avoids certain things so they won't be reminded of them? I thought of moving out of state, then I wouldn't have to be bothered of thinking of the past, and to just move on.

Also, I do have a history of having anxiety. I have social anxiety and OCD. I have a hard time talking on the phone, and feel nervous talking to people.When I don't have steady contact with the public, the social anxiety comes back.

If anyone can help, it'd be really helpful.

Can anyone help? I thought it was possibly PTSD, though the events that lead to how I feel were not typical "traumatic" events.
