First of all a friend (same sex or not) being interested in you is NOTHING like a sibling or relative being interested in you. If you are a true friend and still care about this person you need to say something to her privately. Don't play the victim card because she isn't doing anything to you, if anything you should be flattered that someone likes you (even if you don't play on their team, you know what I mean).
It doesn't matter what medical issues or disabilities she has, she is a functioning human who needs to be told, like anybody else, when they are doing something wrong or upsetting. Why are you afraid to say something to her? She is obviously not afraid of upsetting you by doing what she is doing and it's not like she is going to slap you or something.
Just pull her aside either at school or after and tell her something like "...look Jamie I've always enjoyed being friends with you but you are making me really uncomfortable and irritated by ogling me, the comments you make to me in person and on FB (and what ever else she is doing) and you need to stop." She may or may not become upset and if she does it will be because she is embarrassed. Do NOT apologize for anything, because you are doing nothing wrong by telling her.
Wouldn't you want to be told if you were bothering someone?! The friendship may continue but it might be different to where you just don't spend as much time together anymore. Finally, don't you become a bad friend or person and throw her under the bus by makeing fun of her with your other friends or being nasty to her.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
