I need a nickname for Carmen!?

Ive got cari and cami and im not to crazy about them. People name me car car, car, cam, carm carm, carman, carmal, and things like that. I DO NOT LIKE THAT! It really offends me when they say men or carMAN! I hate it! :( Please help me find one if not tell me if u like carri or cammi better? CANT CHOOOSE!! Well please dont be silly. Im trying to find a great SERIOUS nickname for me. I also want it to close my name. My friend gave me the idea for a nickname when she said hers could be Bree because her name is Brittney. I want a name close to mine like hers! Please comment!
