How to move on?

I’m holding back to those good and bad memories... I don’t feel like I’d ever let them go . I wanna set myself free from those memories because I’ve had enough my brain says, but my heart says you will never get enough of it saying nothing will be enough until you find peace within yourself . I wanna leave those my old make up, clothes, feelings not because they are old because they don’t fit me anymore , but I’m clingy to those things. And when those clothes make up don’t fit me , I feel sad. I feel destructed because I’m broken person. I’m just trying to build myself from the beginning and it’s not easy....
