Sue, Wow! You have had a time of it. Your story sounds a lot like my boss's story. Too many bad things happening to nice people. I hope that 2013 is decidedly better for you on a personal level. With all that has been going on, it is definitely important for you to make time for you. It will help you to better be able to be there for those who need you. So do make that a priority!
What a nice idea about the books for your kids. It is something they can treasure and pass down to their kids.
I see a trip to Walmart or the office supply store in your future to get some sort of a tickler so you don't forget to send those cards.
Here's hoping you come back here next December and find you've accomplished all your goals.
