Whether or not you have a diagnosable illness or disorder, I do suggest that you seek the help of a professional. To diagnose Posttraumatic Stress Disorder there typically needs to be a life threatening event, however, many events in life can be “traumatic” and can create lasting effects, such as the case of bullying.
You are at an age that peers have a huge impact on your daily life. Unfortunately the lines of friendship and loyalty can change like shifting sand and a friend can quickly turn into an enemy during the teen years. It is hardest to heal from betrayals that come from those whom we trust and confide in. However, identifying that these folks are no longer your friends is the first step to healing and getting your distance.
The fact that you were so deeply affected by their betrayal that you hurt yourself and contemplated suicide is an indication that you need help getting through this. Please speak to your parents, school counselor or doctor to help connect you with a therapist who works with teens. Someday this will all just be a blip in the story of your life but you need to give yourself the chance to get to that day! Please reach out!
All the best,
Dr. Holly Counts
