Every chapter has to end. Today or tomorrow. If you cannot finish it, destiny will finish it for you. Being rebellious would only hurt you here. Let the page turn after there is a full stop. You can go back to the previous page but only for memories, not for life. Letting go simply means you cherish what you had but there is enough courage in you to seek better. If you don't believe what I say, think of a favorite novel, genre mystery, did you find the secret on the very first page? I found it when I moved on.
