The past often haunts us. The past often hurts us.
The past is history. People may remember some of your history. But you don't have to prove anything to anyone. You don't have to show that now you are changed, or you are improved. There is nothing to prove. Let not the past haunt you.
People hurt us. It's normal. It happens every single day. Get used to this hurt. A punching bag takes 1000's of deadly punches from boxers everyday. Be a punching bag. Absorb the hurt. Let not the past hurt you.
Let go of your past. Enjoy the present - it's depth, it's life, it's awareness, it's joy, it's innocence, it's fun. That's the only moment you can live. Let go of your past.
