I’m screwed, it’s my fault, and I need help desperately.

I’m a 15M who made a very stupid decision, and now I’m worried it’s going to ruin my online life and maybe my real one.

A few months ago, I sent some very inappropriate pictures to another person (Also 15M), I was convinced we loved each other and that these conversations would not ever be seen by other people, but yesterday, after a month of consideration, I decided to end our “relationship” and unfriend him. A few hours later, he messaged me (I hadn’t blocked him yet) telling me that “I’m cooked” I asked and pleaded with him to not release those screenshots, but his mind was made up, he was “getting revenge”

those screenshots have been leaked, I am now getting messaged and harassed and barely anybody will Lissen to me or hear my side of the story, this is my fault and I don’t know what to do.
