Speak up. Otherwise you'll just keep going down the downward spiral of being extremely antisocial. Try to get away from being the "quiet one" while you still can.
I'd time travel back to fifth grade. Oh boy, I do have a lot of advice I could contribute:
"You're going to suffer a lot, but it's going to help you see the world in a different way. You're going to become a hard person, but also softer at the same time, because you've struggled in life, and you always want to be there for people who struggle. You're not going to forgive - and you're not wrong for not forgiving. You don't have to be a saint and forgive those who wronged you."
