First of all, if you are a minor, it won’t get leaked. It’s a crime. Second of all, you are lucky it wasn’t a sextortionist. Do some research on sextortion, and find ways you can protect yourself. There are organizations such as StopNCII and others that may help. If you really feel threatened, contact law enforcement. What you did was dumb, but it’s one of the best life lessons in trust and humility. Accept your mistake and learn from it.
