If nursing school is your top priority, it sounds like you'll have to set some firm boundaries with your family that allow you to dedicate the time/energy you need to put into school.
She's still in the hospital, and she's stronger. I call her and see how she is doing. I visit in between classes, etc but its still not good enough.
Her well-being is being managed for now, and it sounds like she's getting regular visits from your father and your sister. You are checking in with her via phone when you can't be there. Do

What would think is in your best interest going forward?
my sister is also insanely jealous and doesn't want me to finish nursing school. she got angry with me because i'd rather study than devote my life to sitting by the bedside all day long. refuse to be supportive of the dilemma I am in
That's difficult too, but keep in mind that you have to do what's best for you, even if she doesn't want you to finish school. From your post, I'm guessing that finishing school is very important to you, even if your family isn't supportive.
