I'm not sure if my family would have even been able to deal with it, but I wonder if something like this had been available if things might have turned out different with my younger sister.
I always found it so weird that none of her doctors, psychiatrists or therapists ever asked me about anything. We were a year apart and had mostly the same group of friends for so long. I always thought I could have provided a lot of insight if anyone had bothered to ask. Instead what I got was some directive to practice "tough love" and to not let her in if she came home. That was fucked up.
