Oh, and I wanted to say to Jewels...
while I wouldn't pour something on someone...
I do have a temper, and yes mercutio...I do through tantrums, lol.
Usually though after the pressure has built up enough that it needs a quick release so I can reach a more normal state in terms of emotions and stress. The quick release isn't directly harmful to anyone, nor do I smash/break things. Though I often have the impulse to do that (thankfully I have no habitual patterns that feed into these particular impulses, so it's easy for me to NOT act on them).

After the outburst, I'm usually back to being ok, though depending on the situation I may need to go for a long walk first.

To others, these outbursts 'come out of nowhere', and are perceived as me 'over-reacting to a simple thing'. But the fact of the matter is that the stress and pressure have been building up for quite a long while and are over more than that one 'straw-that-broke-the-camel's-back' incident.
