I'm sorry. I've been through this too. One time my mom fell on some glass and cut her hand and I was the only person home and she wanted to take me to the emergency room. Then she v* from fear and pain and the sight of blood and I almost couldn't take her. My mom called my dad and he yelled at me for like an entire minute until I felt bad enough to take her. I felt like such a horrible person.

Maybe you could brave it and go out and see her? She's not sick from anything contagious and I'm sure she won't v* while you're around. And at least she'll say "I'm going to be sick" so you can get out of there.

I'm sorry you're having such a difficult time.
