What should I do!!

Hey so I am really struggling right now. I want to become famous but something is stopping me. In middle school I was a terrible person I said some messed up thing about people and just messed up stuff. Like things I shouldn’t be saying at all. And I’m scared that if I do get famous I’ll get cancelled but like it was in middle school and I changed I dropped all the people who encouraged that and the people who were rude and I have focused on becoming a better version of my self because I feel terrible. I was trying to make those people laugh and think I was cool it obviously wasn’t worth it because now it’s taken a toll on my life right now. Like should I switch a career choice. I’m not trying to ruin my life. Do you think the internet will understand I’m not like that anymore. If I explain
