How can I forget about the bad memories of my past?

Forgetting bad memories of your past is tough, but they are a part of you and shape your current self. If you forget them, you forget a piece of yourself. Both good and bad memories can be beneficial to your current life. Don't try to forget the things that shaped you into the person that you are. I've tried this, I know others who've tried this, but past trauma makes you stronger. It makes you more aware of the things that have happened to you, and it gives you emotional strength. Don't forget bad memories-recognize them. Best of luck, and take care.
