Without going into too much detail, I'm trying to get over a long-term relationship with my ex-best friend who quickly replaced me right after the brake up. I'm tired of being stupidly depressed, and want to try to get my bitterness out in a kickboxing class on a punching bag. I've looked up as many similar questions and lists I could find, but the songs either didn't really apply to me or just made me more depressed instead of angry. Could someone give me a song or two that focuses mainly about a girl being rejected/replaced or just angry and hurt about the break up?

I looked up a few of the Riot Grrrl bands' lyrics (which kick ass) along with bands like Jack Off Jill (even more kick ass), but I didn't find anything. Of course, if I missed something, please don't hesitate to say so.

Thanks so much everyone; I really, really appreciate your help!
