My Mistake Used as a Joke

Back on the Ides of March in 2017, I had a substitute teacher for my Biology class, and he let us use our phones for an assignment. I took a picture of that teacher for a joke, but then one student took my phone and deleted it. I did it again and posted it on my social media. What hurts me was that I didn't mean to do it, but then two bullies started laughing about it and making fun of me for my mistake like they didn't care. They told me "STOP TAKING PICTURES!!" over and over again for another three months, and it's been very painful. The two bullies even made more people joined them to make fun of my mistake more and more, which made things even worse for me, and I didn't even know some of them at all. I wanted to cry about it, but people would make fun of me more for my feelings. Also, I told on the bullies to stop with their foolishness on me, but they just kept growing and more people would throw hate and negativity on me. Many people didn't care about my life and my feelings at all, mainly because I was a big snitch in high school.

If anyone's wondering, I'm a college student now, and that experience has been very tough for me to handle. I did let it go and I did try to ignore it, but it sometimes pop back into my mind. Did I deserve to be bullied for my mistake? Did I deserve to go through it?
