Cyber bullied after a day of fun

I had invited a group of friends over on a Saturday day. They had posted videos of us on Snapchat. Later that day my ex best friend had seen me having fun with other friends and decided to tell her friends that I was talking behind their back. They had then each texted me in their separate Snapchat accounts. They had texted me that I’m a stupid snitch, lesbian, atheist, etc… they had also told me that they hated me and threatened to jump me. It was a horrible night after that, which had also affected me for the next several days. I was encouraged to listen to close family members and friends who told me to just ignore it. I eventually did, but other teenagers might not which may lead to bad decisions such as depression, anxiety/stress, or even suicide.
