I was horrendously bullied at school OP, so I can sympathise with how it affects the rest of your life.
I recently came across one of my bullies in a shop, and still felt the fear I used to feel...even 20 years on! For a few seconds, I was my 13 year old nerdy self, eating my sandwiches in the toilet because I was so frightened.
Obviously, I have nothing to be frightened of now...I'm a 36 year old woman, who wouldn't take her shit...I could floor her now
I am, however, still a nerd and proud of it!
