Chris - you see the positive in this and that is wonderful. For years my motto has been "Everything is Temporary." Try to limit your pity parties and keep busy. Get into a routine just like you did for work. Take one or two week's "vacation" then start the job search. In the mean time, spend time with your hobbies and spruce up the house. Little things work wonders. Sew a valance, make some new chair cushions, a couple of potholders or something special just for you.
Things always get better. It may take time, but they do.
