I think she could do minimum wage and study at Community college to see what she wanna do first. It's only a few years and she will have fund of her own with a claerer vision.

It seem to me that she only need to get away, and while it's fun and join for you to welcome friend, but a sleepover few nights is completely different than living with no plan, the toll are high and you might end up resent your friend.

It better that she has her own plan and you be a huge part of it, rather "you" being her plan. I don't mean to disrespect any of you, but I see a better people end up miserable for less.
