<human>: I'll start by saying I feel pathetic for even posting here. The "Event" actually happened in highschool 6-7 years ago. I used to get bullied, seemed normal at the time I repressed all of it and buried myself in study.

I went through counselling after my grandma passed (my best friend), I wasn't a social outcast she was just the only person I trusted. Counselling caused me open up more, talk about my feelings which caused me to mention my past.

The "Event" consisted of me being cable-tied to a railing one lunchtime. It was tied so tight that my blood circulation became limited, it was very painful. At the same time I was surrounded by a large group of students who preseeded to torment me, slapping me on my ass spitting at me. I felt completely alone, my so called "friends" watched on didn't help. I've never felt so embarrassed and lonely, helpless. This went on for around 30 minutes, teachers ignored the situation.

When the bell went and lunch was over I was cut free, but that day changed me. I have trust issues it left me very cold and angry, I didn't tell anyone about this until recently.

So now I'm struggling to sleep some nights, I can't stop thinking about it. The pain comes back especially as I write this, the memory clear as day.

How do I deal with this, I fully accept I cannot change the past, but how do I let the past settle. I just want to move on the past shouldn't be important. I just want to finish University and put education behind me once and for all.

Can you give me a shortened version of the text?
