how to forget and move on with your life

Then make a firm decision to change it. You can give yourself a positive confirmation, for example:

I know I am going through difficult times, but I am strong, intelligent, and persevering. I can and I will get out of it.

I will make my life wonderful and beautiful.

The second step is to take a day off to have fun, spend a few moments of happiness, and relax as much as possible.

Try to make "something" healthy and powerful.

Think for a moment about your body, feel what hurts, and how, what are the emotions, what is missing. Give your best.

The idea here is to prepare your mind to think clearly and constructively so that you can act with enthusiasm, creativity, and positive action.
