First off, I'm very sorry about the fact that you're losing you're job. I don't want to sound all motivator like or anything, but at times like this, it really helps to dwell on the positives in your life and try to pick a starting point and build on that. You did get 18yrs. there which is a great run, and I'm sure you made some good friends and clients, that are likely to follow you. I'm sure once you get out and test the waters, you'll find a new place that you will enjoy to work at. Most importantly you say that you are feeling good health wise. That of course if the most important thing of all. You must praise feeling healthy each day, it's an absolute gift. You also say that you're not the main bread winner, which tells me that you have a good support network at home.
I hope in a few days when the shock turns into strength, you will be ready to build on the assets you have. Good Luck with everything. Just curious, where in Canada are you located as I'm in Southern Ontario.
