You came here for advice, sometimes advice can be tough to hear, especially when it's blunt. Plenty of people have told you that people don't care about what you did as a kid as long as you didn't murder someone or something. Most people give teens a lot of benefit of the doubt, younger than that might as well not exist. If every kid who ever got in a fight, or called someone/thing gay as an insult, or created things considered edgy and cool but is actually pretty offensive was cancelled, there would only be like 5 people on the internet. Yes, cases like that can happen where a small creator gets piled on for something stupidly small and they have to leave the site or something, but you could also get murdered in your sleep tonight or hit by a car crossing the street. You've got to put into perspective and asses the risks vs the chances of it happening and decide if you're going to be afraid or not.
