how to overcome the past of your life ?

I don't think it's possible to forget the past. I think they are etched in our memories forever. But what we can do to deal with that is just learn to accept that these bad things happen for a reason; either to teach us a valuable lesson or to guide us with our future decision making. Do not let yourself get stuck up with that though; you can always make new memories to overshadow the bad ones. Whatever you do, just continue to move on. Eventually, you will learn to live with what happened and you will realized you actually become a better individual because of it.

When you are walking straight you can't look back, physically so the same it is spiritually if you are living a honest and decent life you will live in the present and don't get the past bad experiences get in your way.

It is only possible to think of one thing at a time so when these memories come crowding in deliberately think of something else. After a while it gets easier and eventually those memories will hardly trouble you at all.

It is your choice not to ponder over it. You're the only who can stop this. Why don't you think of happy events rather sad ones in the past then maybe you'll forget the sad ones. It's all in the mind. .your mind does it all but you can control it. Help yourself

Which one do you really want to know, to overcome? or to forget? Cuz they are two different things.
