Bella, I hear you. I have not moved to a new place, but about 7 years ago I lost my job due to a corporate buyout. We knew something was up, but were not sure. We literally had no notice. The pr person came in and said, "we are shutting you down." we signed severance packages, packed up our belongings and left in less than an hour.
It felt awful to wake up the next morning and not have anywhere to go . . .
The only thing I know that helps is time. Have you ever tried working at temp agencies? You can work for a little while and turn down or take jobs as they come depending upon how you feel. Your work with greyhounds sounds really interesting and fulfilling. Have you read anything by Stanley Coren? He is a famous dog researcher in Canada. I saw him speak in Portland. He showed a clip of a greyhound and a racecar. They started on opposite sides of the race track so as not to run the dog over. They raced and the dog actually accelerated faster and got to the other side before the race car. It was amazing.
Here is his site if you want to look at his dog stuff. It is really interesting. (I have no stake in this website - just think it is interesting.)
Hope you feel better soon,
