When I'm overwhelmed with everything going on, my mind jumps all over the place too. Sometimes it's hard to stay focused.
You have a lot on your plate right now. What you are experiencing, in my opinion, is normal.
Denny had a good idea about getting an apt. for now. I know that the complex I live in does yearly leases, but also does month by month leases (although the rent is a bit higher in those cases). But that might be the best option for you right now. It's something you might want to look into. When life gets tough, it's important for 'home' to be a safe, quiet, stress-free place.
And it's good to vent, so keep coming back, ok?
