If its true then at least she did everything she could. At some point you just have to let go if the friend does not want to be saved so that u will not go down with her.
She is truly a saint for trying to help Selena get her health and career back on track but I guess some people can't be helped. That and she's so nice to respond to fans like this!
On a serious note, do people really believe Taylor and Selena aren't friends anymore? Selena is clearly back with Justin and obviously Taylor doesn't approve but I don't think they would end their friendship on something like that. Selena has a bit more sense than people give her credit for and Taylor isn't the type to leave her friends imo.
