You're awesome if you became friends with the people you bullied. If they are your best friends today, then they have forgiven you for what you have done. They saw the better side in you. We all make mistakes, and the people that car about you know that you are sorry for it. What's amazing is that you still apologize every day, to make sure they know you are sorry. I wouldn't have the guts to try and become friends with the people I've bullied, but I haven't bullied anyone and I'm sure I will sometime in my life. We all do even if we don't know it so you're not alone.
