Lou, I'm sorry about the job rejection...but maybe it wasn't the right job for you. Keep applying for any and all positions. I know it's discouraging, but I also know you will find one very soon because you are a strong, independent and determined woman.
I'm also glad to read that your son is no longer living at your h's place. Your sons are going to find that the less they deal w/his drama, the better off they will be and stick to safe subjects.
Hang in there!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
