essbee, it must be really hard to contemplate moving away from the area you love. Your statement "I want my old life back but I can't have it, it's gone" encompasses so much pain, it seems to me.
I agree with Aloha - can you brainstorm ways of staying in your house? I wonder if janster can help you - doesn't she know a lot about property management? Can you rent out any of your rooms? can you move to another house in the same area and rent out rooms?
I made the move away from a 'nice' area full of my friends to much less nice area full of strangers. It was a wrench to leave things, but the plus side outweighted the minus side: our house was much more suitable for a family and by far the best thing of all - selling up enabled us to pay off debts and get ourselves back on an even keel financially. It was an utter relief. It far outweighed the reality of moving to a 'downmarket' area. And also, our upmarket area was getting more and more full of single, relatively properous people. My lifestyle and finances were so different,I was beginning to feel a stranger in my area long before we left it. I hated keeping up appearances and witnessing my neighbours spending money like water while I was scrimping and saving. It just rubbed salt into the wounds.
While fighting to stay in your present house, can you look around to see what sort of place you could get if you move? really look into the areas you'd move to, get lots of details. You might begin to build a good picture of what your new life could be like. It seems to me ( could be wrong of cours) you are in need of a plan for the future - something to look forward to. You have a huge amount of changes happening to you. Some are just going to be beyond your control. When this has happened to me it's the hardest thing to accept you can't control things, but sometimes you have to. Hang on in there, things are moving, and somehow soon you'll see where you want to be.
I hope you manage to sleep better, too. Lack of sleep is such a downer. There's been some great advice on here, hope it helps you.
