Hmmm. What about the idea Wild Coyote and BirdDancer had? Do you have anyone you could call on to help support you? It *would* be really nice to have the cash boost if you can make it work.
I understand your fear. My ex-H had to go (many hours) away to work for 9 months(!) (it was supposed to be 3, but either way...). I was in a very rough place when he had to take off. My son was 13 at the time and the only support I had was a weekly T session -- that I hung onto for dear life as you can imagine(!) I was very nervous also, so I understand.
