Ouch. I feel the struggle. My mom was a single parent and I know it got rough for her. Just know that despite the fact that none of your kids are ever likely to thank you for all that you have done and will do for them, they all have a sense of gratitude for it. And who knows, maybe you will be that lucky parent that has an insightful child that manages to think to thank you for everything. Then again you chose Parenting, Sports, and Emotional as your genre's not fantasy... Anyway great piece, definitely made me feel for you.
