emotional

I hate how emotional I am. I get upset over the smallest thing, I cry over a slight shift in tone, I get angry over the slightest bit of desinterest. I cry so easily and the stupidest thing is, I won't stop until I get what I want. It makes me want to rip my guts out, do bad stuff to myself and others. I cry over sad things, over things that should make me angry, over jealousy, over stupid things and over funny things too. Why am I this emotional? Why do I start to cry so easily? Make it stop. Please.
