In particular, when people are nice to me.

For example, when my family sung happy birthday to me last year I almost broke down into tears because I felt like they were so naïve for caring about me (or at least pretending to). I can't do anything but hurt people, I've been nothing but a cunt and a burden to them since the day I was born, why would they do something like that for me? Just because of moral obligation or tradition? I don't understand. I feel bad for them for being stuck with a worthless piece of shit like me and feeling like they have to like me just because I share some of their DNA no matter how disgusting of a person I am.

Not sure if this can be attributed to BPD but I didn't know where else to post it. Sorry.
