I do not mean to attack, but this is completely untrue.
Everyone i know who has healed their specific trauma has escaped and created a much happier, much more fulfilling life.
You cannot make a decision to close the cycles. They will continue until you heal them.
It is a higher order that keeps the cycle repeating, so it is not breakable through will or choice.
Forgetting is quite easy.
I do not know how to explain this to someone who has a part of them that keeps bringing up the pain over and over and over.
So, you heal the trauma within you, and you also work with (tell that part of you to shut up, it is really out of control) the inner critic then that past just, like, fades away never to interrupt your life again.
A book that really helps is
