By the time I was 9 years old I was self harming and suicidal but the teachers who knew did nothing, not even let my parents know. By my teens I was wild and as far as I can guess now had mixed and depressive episodes, and again was very suicidal. Yet I hid all this from my parents out of habit I think as my abuser threatened me with death if i told anyone (I was abused from a young age by a much older cousin.) The PTSD and Bipolar are hard to tell apart. I am amazed now that no one really picked up on any of this until my friends in my teens, but they just thought I was crazy. In year 12 I was voted the person most likely to wrap their car around a telephone pole. Bit of a hint there I guess. Wish I had of received help sooner as I would have avoided a lot of fallout. Twenty years ago was a different world in regards to mental illness though so I don't really blame anyone except my abuser.
