There is no specified time, given by any expert that how much time it takes to recover from something bad that has happened in your life before. But you have to understand that “It gets worse before it starts to get better”.

And that is how it works, you will be haunted by the pieces of the shattered glass, which are still lying on the floor, and you are afraid to go in that room because you are afraid that you might get hurt.
Sometimes, you need to carry a broom with you and clean the floor yourself, you need to understand that maybe you will step on one or two pieces of broken glass and you might get hurt, but after that it will never happen again.
Your present is a gift for you, and past no matter what it was good or bad, it is gone, long gone. It can not hurt, it can only haunt you, and you need to clean that room where it stays, you have to make space for other things, better things.
