Any suspicions plaguing you these days, bongman? You're describing an uncontrollable temper, which is nothing to be afraid of but should definitely be handled, as it has the capacity to crush your existing relationships with people. So you're a little weak-minded? Who isn't? Before therapists, people handled their problems on their own. Some simply acted out the unease in an unhealthy way but you're smart enough to know how to relax. Some terms that come to mind:

Self-reflection, self-affirmation, self-control, etc. You don't need professional help. Who knows you better than yourself? Just think, and be aware of irrational thoughts. Even if it is merely something you would like to think of as "irrational." For example, when I think about how much I hate my mother, I label the thought as irrational because deep down I don't want to hate my mother. You're skipping a few steps in the thinking process. Just slow it down a bit.

And hit me up on AIM, if you want.
