When I'm in a high mood I'm extremely manipulative. I'm not sure what causes it though, because I also have BPD. I just want to get what I want when I want it, no matter what. I have lied and screwed over whomever necessary to get what I wanted. I guess that's more along the lines of BPD. I feel bad after I come down though, unless it was a stranger. Then I try to justify my actions to myself.
