You sound much more positive, that's fab! Do whatever makes you feel better, and I hope they phone soon with some constructive ideas. And you're right, staying occupied is a good idea, just do whatever you feel like doing. Isn't DH coming home soon?
I'm really proud of you, don't take that the wrong way, I know how hard it is though to ask for help and be so vulnerable, when all you can think is that no-one will care and everyone will be better off without you. The more people you talk to about it the better, you are never alone.
