A close friend of mine (who has been diagnosed schizophrenic, bpd, bipolar) used to be one of my main triggers. One minute we were as close as can be, the next we wanted to kill eachover. It was bloody intense. What made it worse was that he picked up a coke habit, and he turns into a total manipulative arse when he's on that. It's got to the point where (like so many other people I've been friends with) we hardly talk to eachover. Now he's gone everyone and everything else is starting to get to me. So it's a lose-lose.
