Being ignored is the big one.

also being mocked or criticized for something I can't change.

Following on from the first one, being in a group of people and seeing other people address everyone else in the group while avoiding me like I'm not there. Maybe I imagine that sometimes but it really hurts and just makes me want to disappear.

A lot of those tie in with things that happened at school and at home while I was growing up. I remember once an English teacher at college went round the whole seminar and asked everyone to define poetry. It was actually a question I probably could have answered even though I was usually mute but he asked literally everyone except me. In fact I'm sure it was at college that my BPD came to full fruition. I have so many flashbacks to that time and they all involve social exclusion or rejection of some sort from peers and teachers. I feel like I must have been a freak or something and I've never really felt like a complete person since.
