I do this too. The other thing I do is that I won't answer phone calls or return phone calls from people I care about and really want to talk to. It is weird because I will be fine and then the phone will ring and it is like someone flipped the anxiety switch on full power. I'll panic and not answer. Then I get nervous every time I try to return the calls. I love my friends and I want to bring them closer to me but I do this and push them away instead. I don't know why I do this. It makes no sense to me. I have been doing better lately.
