Lyn,
Wow! You have taken so many huge steps toward your goals. I know your children are seeing these things that you are doing to make your life better and they are learning important lessons from them. What a good role-model you are! These things you are doing aren't just making life better for you and your children now, but they will help make your children's lives better as they learn and grow.
I sincerely hope everything goes well with your Monday interview. And good luck with your school application, too. What degree are you going after?
