If you had a bad deal of a personal problem in your past, learn from it and never do it again. Take your painful past as a bad deal, move on to your life and move on. Be happy! You have many chances that never end in your entire life. Be optimistic.

However, I Advise You

However, your life was in high school and you graduated from it. If your experience was a painful and hurt one, don’t be like Batman or Batgirl in real life, because the nice people who want a second chance will be hurt because you thought of doing the right thing. Maybe, they felt the same as you did, fed up, and they wanted to make amends with you. You will be the same person that hurt you. One simple quote, if you get revenge, then you will be the same like them, (the people who like to hurt people’s feelings). I advise not to do it, because you will regret it for the rest of your life and you will be the same as the bullies who hurt you. If you do, you also will be a bully. Move on, give nice people second chances and be happy.
