I was a bully . The past keeps haunting me even though I apologized. What should I do?

You should forgive yourself and move forth. I was bullied and I have forgiven my bullies. As long as you have learned a lesson in the process. You know that it was wrong and you now know better. Some bullies don't even acknowledge that what they did was wrong and they move forward like it's nothing. You are able to advise somebody who bullies others because you know better. You can even maybe go to your local community hall and address the negative impact of bullying and you can also tell them that you used to be a bully but now you are a better person so that the light can keep on lighting, so that there is less hate in this world.

Live your life the best you can be. Try to distract yourself with something else, but if that doesn't help, try to make up for it. Be really kind to people. Do favors for them.

Sometimes as people, we punish ourselves for what we've done in the past, whether it's said or done something wrong, doubted yourself or bullied others. Nonetheless, we forget to forgive ourselves in many scenarios.

Accept the past, it happened, it won't change. What matters is the future. You apologized, that's the first step, now you need to accept yourself. What you did was wrong, but you can still make a difference. You can volunteer for bully prevention programs if you wish, or just share the negativity received from bullying with others to try and prevent it!
