My (25f) little sister (16f) wants to move in with me across the country and idk what to do.

My mom is unfit. I moved back home and it’s even more apparent that mental illness and lack of treatment have made her unfit to be a mom. My sister turns 16 in May. I could make it stretch financially. Ik we would scrap by but my sister would be happier.

Idk how I’d get her into school but after seeing everything I’m at a point where I’m looking at prices for another ticket because this isn’t okay. I don’t want to put my mom on blast, but it is not okay. A lot of it is how badly unkept the house is.

So yea idk it’s a big responsibility but I’m thinking ab it just so she can be safe. There’s a lot of uncertainty and that makes me nervous. I’m not rich we would def struggle but materially she is very spoiled. Idk if I could handle raising a teen. Mentally and financially. But I feel more and more need to try and do so. Even tho I know couldn’t undo it if I got overwhelmed
