A good rush now and then can be fun, whether or not I seek it out depends on my mood. Adrenaline rushes when already having anxiety is not a particularly wise combo unless I want to get really angry and destructive.
@Raythedevil: Indeed. I'm familiar. And that's a pretty decent analogy for it. My usual response to when I get like that is to just leave and go outside to calm down, possibly grab some things I'm not attached to before I leave to smash and vent some of that anger.
@Madeleine: That doesn't help me, I've tried that. Meditation sometimes works. I've had a couple occasions where it didn't. When that doesn't work, the only thing that seems to get me out of it is an ability to vent my anger in some way and get a flow of positive energy from someone or something else. Most commonly has been my eldest brother, who has really bad anger issues(my anger issues are pretty much non-existent, as I mentioned this is a thing that has occurred so few times I could count it on one hand), so he tends to be really understanding of the whole thing.
