Hi there,
There is no straight forward, easy method to do this, and it is different for everyone.
The best way I could suggest would be via therapy. there are lots of different types depending on the problems it presents you, like specific abuse therapy, or inner child therapy, etc, or a combination of different types.
Therapy basically helps you learn from it, realise it was not your fault, accept it, and learn to move on. You will forever have the memories, but it will stop it from hurting you.
Anyone who has had to deal with child hood abuse, or abuse in anyway is a strong individual, and will survive it if they choose to.
I fully believe that if you reach out for the appropriate support then you will come through this and you will be able to look to the future without your past hurting you.
