I was first diagnosed with some form of BPD early in high school.  One of my biggest problems with it is that I have a hard time interacting with people.  At first I can be fine but then as if a switch goes off I do a complete 180 over the span of just a few seconds.  Along with that, I get suddenly attached or unattached from people for no reason (its not healthy, I know).  For example just the other day I was talking with my friends about just random shit and one of of them mentions he fucked this one girl.  I hardly know this girl, I never think about this girl, the only connection was that I went to pre-school with her and we wound up at the same college, no interactions with her between the two periods of time or anything.  Now, all of a sudden the smiles gone from my face and I'm almost in tears.  Thankfully my roommates didn't notice it this time (they're very good when I have an "event" or whatever you want to call them, I just don't like bothering them with my problems when it feels unnecessary, I hate bringing people down with me).  Anyways, thank you for listening to me vent, it does help communicating with people who get it.  I'd love to hear what some of you guys think

*Edit: It only lets me pick one flair but its definitely Seeking Support/Venting
