When I was about 8 or 9 I put my head through a glass window on purpose and required stitches, I could never talk to my parents as they were too busy doing other things.

Sexual abuse by my brother from the age 9-16 too.
I was bullied throughout school.

I always knew I was different, I could never make friends like other people.
I had always struggled and always kept these feelings to myself until 5 years a go when I was constantly self harming and I went to see my GP who referred me to see a Pdoc and he diagnosed me with borderline personality disorder, PTSD and depression.
