I don't really use the forums that much, or interacted with you either so sorry if I misunderstand but;
You are on the right track by apologizing and having the ability to recognize there is a problem and actively go about doing something about it.
Although probably not to the same extent, I can see how going through a rough patch in your life would spiral your behavior in the way it has, as I have to admit my own behavior has been less than steller over the last few months due to a multitude of factors I am not proud of.
While you possibly will not get the answer you are looking for from the people you have upset or hurt, know that it was at least the right thing to do and you can use this opportunity of a clean slate you offer as a way of proving yourself as the person you want to be, not the one you feel compelled you have to be. Not everyone is going to like or agree with you, and that is okay because not everyone will. Sometimes it is like that, and you just need to take a step back from everything and put things into perspective.
I am aware that changing your mindset can be a difficult task to stick to, so I wish you good luck with that as it is something I am personally battling with as well. You will see a positive effect over time and it is worth doing.
Like I said, we've not really interacted, but if you want to talk or vent about things, my DMs are open on Discord, in-game or on the forums. I can't say I have the best advice, but sometimes you need someone to talk to.
