I don't mean a violent trouble maker, I just mean the sort who constantly starts arguments for the slightest thing, is just sort of insulting without thinking about it, or just a naysayer?

I find myself disgreeing with small nitnoid things, and leaping to respond to the slightest insult (especially in the internet) with even greater insults and cutting down of the other person's ideas.

It's really distressing. That and my stubborness and inability to realize when I am doing it is causing me a lot of trouble in work and life.

I think I am BPD, and I think my sister id BPD, and the two of us can not be in the same room because she makes a statment I think is stupid, or insulting, and I respond by explaining why it's stupid, or with an insult of my own, and we very quickly escalate to (generally) my cutting her off and leaving because seh's frothing at the mouth. I once pissed her off so badly she drove two hours, sending me text messages the entire time, as she was driving. I finally turned my phone completely off so I could drive myself.

And my life is a one sided version of this most of the time. When I am able, I talk as little as I can, because I end up preaching and get in arguments and can't get out of them. I absolutely have to win them, or I'm mentally ruined. And when I win them it's a phyrric victory.

So...what do I do? Do you have these problems?
