When you push down strong emotions, and feelings, be it anger,love, or pion, where does it go?

I think that everything piles up and eventually comes up and you have to deal with it.. I think that is why they say it is best to deal with it now, before it blows up and becomes more of a problem, or whatever than before you just pushed it away... I don't think it is healthy to have something weighing on the back of your mind, no matter how hard you try, it is impossible (for me at least) to completely remove something that is bothering me w/o dealing w/ it....
