i know i shouldnt be doing this so please don't respond telling me not too.

I have never taken xanax before and have heard that it's great and gives you a great feeling. I only want to take it once and get that good feeling for a least a little (I suffer from depression). I am going to take 2mg. I am a female, 110 lbs. How should I expect to feel? and after how long should I feel the effects?
