That's fair.
regardless of her reaction you have done the right thing, imo, anyway, and have alleviated yourself of the responsibility you feel you have because of how much you care for her. If you are close like you say, it's doubtful you will alienate her by trying to help.
after some more thought, have you talked to one of her immediate family members with your ideas and thoughts? Maybe others close to her have similar feelings about the situation.
