I have a weird trait which I'm not sure is BPD related - maybe you can weigh in on this. 

Basically, I am terrified of people finding out things about me. Even with friends, I tend to not tell the whole truth. Even innocuous details like where I'm going for lunch have to be disguised. I feel that if people know anything 'real' about me, they can blackmail me (?!) and smear me. But this is weird, because 1) nobody would dedicate their life to destroying me 2) I'm not generally a paranoid person; I don't make sure my windows are always shut etc. 

I start to hate anyone who 'knows too much' about me. For example, if I confide to someone that I have a scar on my leg, or that I am on meds, then I start to resent them for seeing the 'real me'. And I become quite paranoid - I try to find out what they're doing, whether they're telling anyone about what they've found out...it's crazy. 

Do you guys deal with this? If so, how?
