If your family's out of the question, then how about talking to your friend's parents or your sister's friend's parents? Someone that she would want and trust to live with. Or maybe you could check out some foster families to make sure she'd be going to a good place? I guess it kind of depends on how old she is, but no matter what I think there should be some form of social welfare that can help you at least...
And I'm really, really sorry to hear that you have leukemia, and I really admire how strong you're being. I know you've probably heard this a thousand times from other comments, but I genuinely mean it. (Seriously, I'm in tears just from reading this).
Awee hunny, =( that's no fun, I'd offer to take her but I'm not old enough, lol You could always give her to a close friend, or uncle or auntie, you know? I'm kissy by the way nice to meet you and good luck.
:( It must be really hard. I agree with everyone else...close friends...distant family. Maybe she has someone in mind? I know everyone says they're sorry..but it must feel totally insincere. but, I hope you live what time you have to the fullest and love every moment you have left :D xoxo :)
I'm sorry to hear that.and I'm mean it. On the other subject about your little sister. why don't you talk to your best friend or your trusted person that want to take care of her or take a responsibility to love her as sister. Or you can give your sister your money or your plan after you gone. And how old is your sister?
The words "I'm sorry" must sound so insincere, 'specially typed on the internet, but I really do mean them :/
Scarlet Bell pretty much covered every kind of person you can trust your sister to be with, so maybe pick your most responsible/well liked/best choice of a family member/family friend that you feel she's safe with.
Sorry to hear that you have Leukemia (although I'm sure that's not much condolence) but you sound as if you're taking it really well and I admire you for that, you're really strong (it seems).
On the subject of your sister though, I agree with Scarlet Bell too but just make sure that it's someone you trust as well as someone your sister knows and would like to live with. Maybe ask your sister who she'd like to live with and be sure that both of you are happy about it.
Grandparents? Aunts? Uncles? Cousins? Best Friends? Family Friends? That's all I can think of. If worse comes to worse adoption to a random family would happen.
...you're going to die? Sorry if it's not something you want to talk about, but I am fascinated with death. What's it like, knowing that you'll...well, die ? o.o
(I'm trying not to be insensitive but I'm really fascinated)
