My best advice to you is to STAY with it. The most common thing that happens is that people overwhelm the person with the loss with tons of well meaning things AT FIRST. This usually is very hard to deal with well b/c there is so much denial and anger, it's flat overwhelming. But as time moves on, so do people. Other people, that is. Then the person with the loss is left to deal with the loss pretty much alone at the time they MOST need someone. Everyone elses life moves on, and yours is expected to also (whether said or un-said). It feels like a betrayl of sorts and is just so hard. Moreover, DON'T (PLEASE!) say things like "you can always try again" "it wasn't meant to be" so on and so forth. I know people mean well but it deepens the pain of the loss, not lessons. It is absolutely heartbreaking and nothing anyone can say is going to take that away. But you CAN be willing to go the depths of the darkness and hurt she feels WITH her, cry with her, hurt with her and "hold" her pain with her- IF you can and want to be that kind of friend and support. Instead of trying to move her away from thinking about the babies, (if you're present physically) help her moourn them by talking about their intended names and plans and all the things that are now lost. She will cry hysterically (which makes people uncomfortable) but she needs to. That's really the only thing that will altogether help. In the meanwhile, if you can afford to send flowers to her house or something like that, it helps. My sister did that for me and it was surprisingly touching. This women just needs someone to "get" it that this hurts like hell. She will eventually get through the worst of it, but don't rush her through it.
As far as work, I don't know much about the legal end of things. But if she left for medical reasons then they are going to have one heck of a time in court for not hiring her back, even if their reasons are justified otherwise (such as financial b/c of the economy). Honestly, my mother won a lawsuit that way. But, it is long, tedious and expensive in many ways. And in the end they'll probably just settle out of court. Why don't you look into for her one of those pre-paid legal services? It costs about $30-$40 per month, which even with one forceful letter they write her employer might seriously pay off. She may very well be right that what she needs is to get back to work. Hope any of this helps- N.
