^ yeah, and in the case of mental illnesses that develop like this.. staying close and being supportive is much easier said than done as those who suffer this sometimes become difficult to be around, cruel, aggressive and even violent. I also think bringing them to treatment can be easier too when people are more financially dependable (since they quickly lose their jobs over displaying behavior like this), it is much harder when they're financially independent (as I assume Magdalena still is), have managed on their own for a long time and have the means to keep loved ones away.
I just wouldn't be too quick to judge their family or friends, or even assume that she is alone.. if we're disturbed by two or three 40-second videos, I really don't think anyone, no matter how deep their admiration is for a stranger who happens to be a well-known model, would endure even more volatile and bizarre in-person behavior, let alone have the guts (and financial means) to intervene in a way that is legal.
