I think maybe i shouldn't have been my sister's guardian

Hi everyone,

Things don't really go as planned sometimes, right? My mom passed away about a month ago in a drunk driving accident. Now my 12-year-old sister is with me, and she's going through a tough time grieving her mother too. I'm still just a college freshman trying to figure out how to take care of her and help her deal with everything. She goes to Al-Anon teen meetings, which seems helpful for now.

I'm also trying to get her to see a counselor, but she's pretty resistant. I'm not sure what else would be good for her? Like, can I leave her home alone? Maybe it's okay for me to do that? Can she walk to school and make her own lunch? My schedule this semester isn't set up for having a kid around-I work nights as a night nanny where I basically just sleep at someone else's house. Should I try not to leave her while I'm working?

For now, my roommate stays with her when I work, but she wants to go out and party eventually. Plus, my sister needs her own space soon anywya, so I'll probably have to move out. I don't know what to do next. If anyone has advice about kids around that age or dealing with this kind of situation, it would be really helpful. I didn't expect to become a guardian this year
