Uncomfortable

Today during a assembly I was answer questions during the assembly and there was all different grades and I’m a freshman. Then one of my friends turned around and told me to pull down my skirt. See my skirt wasn’t like super high or anything it was just like it always is. My friend then told me after the assembly that a group of junior boys were trying to look under my skirt. To be honest I’m not ok with it. I didn’t say anything to anyone because I was worried that someone would say I was overacting. I felt scared and unsafe the whole day. I still don’t want to go to school but I have to.
