Even though I have no idea who the bullies are, I just lost all the potential respect I could've had for them.
As for you, however, there is no need to apologize. You are strong for going through these things, and being so open about it. Whoever bullies you is weak. So weak, that they should be kneeling for you. You're not supposed to apologize, you're supposed to laugh at them for being the pathetic, clueless insects that they are. You might consider your own previous moves as clueless too, but in all honesty, single mistakes happen to everyone every once in a while. Sometimes, we just don't think. That is nature, not desire, and you are not to be blamed for something that happens without yourself being able to control it. If this single event leads to further events, you are not to be blamed for those either, as they were never supposed to happen in the first place. The bullies however... They decided to dedicate minutes, hours, days, weeks, months, I don't know how long, on trying to make one specific person feel bad about something that they are not supposed to be held responsible for. They decided to act that way. They did not have to. Therefore, they are the ones who are supposed to physically come to your house and give you a big hug and an apology as soon as possible.
So, even though you're not supposed to apologize, if you still think you are, I can tell you that you are already forgiven.
