No wonder some people hated me back then as a kid, I was overtly toxicly positive as a kid

That wasn't your fault, kids aren't supposed to be responsible for shit, they usually don't even know if what they're doing is right or not. Whoever hated you were bunch of assholes, and if it was other kids, they were just yea kids being assholes as kids, parents failed them and you in that case. Again, not your fault.
