The whole situation is just awful, and imo she isn't getting the help she needs.
To cut a long story short, her hubby of 19 years has left her for another woman (although not quite left yet).
She is broken, just in bits and there is no consoling her. She has seen her gp but he has just uped her usual anti d's, which imo have never worked for her anyway. Oh and she saw someone at relate today, but thats it.
She is constantly threatening to kill herself, probbaly because it gets her hubbys attention, but also becase she wants the pain to end.
She came here this evening, drunk, and hysterical, begging me to make it all stop and make him want her again 
He's broken my friend, and i'm not sure she will ever be well again.
