Am I wrong for constantly thinking about people who've blocked me?

For some of them, it's been years since I wronged them. I don't mean to make excuses for myself, but it just seems like such a long time to hold a grudge. I wish I could just have the opportunity to talk to them again, to show them how I've changed, and how I'm sorry.

It's only a few people, but it still makes me consider adjusting my voice and just making a new account so I could get another shot.
I just wanna be friends with everybody!
