I would have folded as well. You have to understand that every1 else is short as well. With your stack size, and the fact that the blinds were passing you I think you could have waited a few more hands. Its better to be the aggressor with far less, than be the caller with no fold equity. A K Q and half of J highs beat you. i think player dependent, any A or suited K high or better including any 2 Broadways is a call. I mean no disrespect here, but with under 15bbs you should easily be able to know what to do. Always think of villian ranges based on their position and situations. Good luck man.
