I have been a victim of cyber bullying when I posted an opinion on a video without thinking that it.would cause any problems because of what had never occurs to me. I was smear campaign on the video has false report made against me meant to intimidate me. Now I have a hard time being on social media without going into full blown panic attack or anxiety attack before the flashback begin to happen. Could being a victim of cyber bullying cause a person to have pstd?
