hiding things from myself

I spent today organizing things at the house here. it's weird going thru my old stuff i realized it seems i like to hide things from myself that at the time make me so happy(so they can make me happy later). whitch would be great except life always get's complicated and then I find myself hurting because those happy thoughts are so unreachable now. I am glad I stash these memories away the good ones and the bad ones because my mind forgets so much. It helps emensly with perspective. Still sometimes i wonder if it might be a depressive act. anyone else do this? is your experience the same?
