I am 15 too and at the end of last year my friend told me she had been overdosing on panadol.
I didnt tell anyone.
Except she started getting very sick and i told a teacher at school.
She got over her depression but i started getting depressed.
I have good parents and great sisters who all wanted to help me thru the hard days.
I used to cut and all the rest of it but now i am starting to get better... and im taking anti- depressants and seeing a psychologist and having lived through it i want to say that u need help.
Maybe ur parents just dont realise and u need to make them realise by getting help from someone else who will help you tell ur parents.
Feel free to e-mail me anytime.
I always want to help.
Just be strong.
