She saw it...

[NauniiNarcotic]

My older step sister saw the scars on my legs... I have literally engraved the word "hell" on my leg...
When she saw them... She told me to tell her a good reason not to tell Mimi (mom)...
I said very carefully not trying to encourage her to go by saying something stupid like 'If I don't I'll kill myself'
" You know how it feels when you get in trouble with didi (dad) and he complains about it an breathes down your neck for a week? Well... Imagine, every single demon... Fallen angel... Reaching up above the burning firey depths of hatred's core and dragging you through hell... While 10,000,000,000 didi's were screaming at the top of their lungs at you, when not only that you can hear and feel the burning screeches of pain running through your veins... Sometimes I need to release the pain to make this journey I'm surviving a little easier to endure... I was being creative though... -chuckle- it makes me feel better.... Like releasing pee after a long car trip..."
She wasn't laughing as I thought she'd be and stormed out my room... I am afraid she'll tell Mimi... What will I do if she tells my okasan (mom)?

You're wording is a bit odd, you're german but use Japanese words. O.K.

Anyways, if she tells your mother then so be it. Maybe it's time for you to get the help you need. Sometimes it's better that way. Most parents react differently to finding out than the children expect, so it might not be as bad as you think.

Good luck!
