Rysmom,
Don't be too hard on yourself when you do have waves of sadness. Sometimes you will be sad. You are human. As long as you don't wallow in the sadness and you find a way to snap yourself out of it you are still moving forward.

How was steak with your mom last night? I hope it was yummy. How was your run today? I used to be a runner until I effed up my knee and herniated a disc in my neck. *sigh* Your class sounds interesting. Have you decided what country you will be working on yet?

Take good care of yourself and your boy. Happy TGIF!

Look not mournfully into the past. It comes not back again. Wisely improve the present. It is thine. Go forth to meet the shadowy future, without fear. {Henry Wadsworth Longfellow}
