FoxyCleopatraa is right. nobody knows. and it's not our job to care about that. don't get me wrong, of course I want vlada to be healthy and happy forevermore. but she is twenty. she's old enough to know what she is doing.
btw I would still support her even if she would be anorexic. don't forget this ia a mental illness that you don't "choose" to have. you just get sick. and you can beat anorexia with the right treatment. vlada isn't vlada because of her weight, she is vlada because of character. and I will love and support her come what may
