im sorry Eva. so sorry. reading all of this reminds me of what I've done to my mother the past 9 years when I was much too old and should have known better.
some humans, it seems, have a self destruct button they cant resist pushing at times. I hate to sound corny but I think it's from lack of love of self. the thing is the deeds affect others.
I hope your daughter gets better and things turn around.
