I'm with skysidhe. Go see a doctor first. Find out if there's a physical reason for your emotional state. I know at one stage I was carrying on like a fruitloop and it was all because my body couldn't cope with the birth control method I was using at the time. It caused my body to store iron which then revealed that I have a gene which means I'm more suceptible to a particular liver disorder...blah blah blah...what it came down to was my birth control was causing me to be eratic in my behaviours to the point of breakdown. (the stress I was under at the time certainly wasn't helping either)
Anyway, that's my blurb on this thread. I hope you get things sorted out soon Munchkin. Maybe you should check out the pms thread?
