I don't know what I did right, but my little sister follows me everywhere, does everything I do, thinks everything I think, etc... It's getting kinda creepy, and I don't think this is any good for her at all.

I thought it was okay when she started wearing my old clothes, listening to my music (which no 11 year old should listen to in any case), adopting my insane mindset, and possibly inheriting some of my disorders, it seems... it got to be too much very recently. A year ago I changed genders from female to male. A month ago, she changed from male to female. She didn't show any signs of this behavior before, but very recently has said she's a girl. That can't be normal. I know I've felt wrong in this body since I was 6, and it showed.

A little sibling isn't supposed to be THAT much of a copycat, right?

I feel like something's going wrong.
