Well, everything takes time. Just wait for the "tamang panahon" and you'll realize little by little, you are able to forget some things that are tend to be forgotten. Forgive and Forget, let go of the past, diba sabi nga nila, you can't move on to the next chapter if you keep re-reading on the previous one's kaya you have to move forward and make sure the lesson behind that mistake will be implanted on your thoughts :)
