What do I say to my friend that her mom calls her a mistake?

[tobylove4]

So my best friend in the entire world is sitting in biology and starts crying. I ask her what’s wrong and she says that she never should have been born and that her mom calls her a mistake. She says that after she was born, her parents divorced, her dad hates her, she gets screamed at whenever she does anything wrong, while if her sister does something wrong she gets “babied”, then she still gets yelled at when her sister does bad stuff, she gets blamed for every thing and is constantly called by her mom a mistake. She has talked about wanting to die and that is the last thing I would ever want to happen. So I try to tell her that it is not her fault, etc. but I get the feeling that she thinks that I don’t understand. I really want to show her that she has people that care about her. I was thinking that I should write her a personal letter saying that she has so many people that care about her, but I don’t know what all to put in it. Should I even do this? What do I say? Please help
