first off, (((((((HUGS))))))))
sorry, things sound rough. do you have a T you could talk to? anyone? there's a post in the sourcebook with an amazing trick for eliminating negative thoughts, and there have been lots of positive reviews (havn't tried it personally). it's at:

that's one way. does writing things down help? maybe to sort out your feelings? i only write when i'm upset. i pick up a journal, and start out by saying how i feel. even if there's no word for it. sometimes i'm not sure, so i just rate it from 1-10, one being the worst. and try not to get frustrated if you can't think of an adjective for your feelings, because that was hard for me to learn. write out anything you're afraid of, annoyed with, etc., and write letters to people (you don't even need to give them away). just explain what's bothering you. sometimes getting stuff out of my head and onto paper helps me get rid of them for a while, until i'm ready to sort them out.
during crying fits, i tend to lock myself in my room. i either go under the covers, and i always sleep with a giant teddy bear, because i do most of my crying at night. it's okay to let yourself cry; don't try and stop the tears. it can be relieving.
i'll try and think of more, but good luck. hope you find something, and i'm always here to talk if you need me.
love, tara.
