Holding On!

There are times when you tend to think about your past.
If it's good , you tend to enjoy the moment.
If it's bad, it keeps pulling you down, it keeps hurting you, it keeps on bothering you, it stays on your mind, it doesn't let you anything else, it just fu**s you inside out.
And you if the present is tough, it will fu** you even more.
Even if you have tried hard to move on, even if you have decided, you won't let the past affect you. It just comes back haunting at you.

I think it's human tendency.

What do you do in these situations??????????
