Yep. First thought that popped into my head was, Could all this medication switching be the cause of her problems? But even if it isn't, with all that changing how is psychiatrist going to figure out which one is the cause/ or not working?
Oh, my. I hope she starts doing better soon. Those 4-5 hr nights have got to be taking their toll on you alone. I think you've made the right choice in having the holiday dinner at home. (too bad you can't have your meal out though)
