What to do

What to do when your the only parent in your child's life and you are called to be two different places at the same time. One which requires your presence and the other is just having your presences there for moral support for your child. Omg! I can't always handle not being able to be at every one of my son's game and having him there by his self. That is the worst feeling ever. Will he grow up and remember how I wasn't always there and talk about it over Christmas dinners or will he say my mother did her best? What happen to big brothers and Big Sister programs? I wish I could rent a dad for part of his up bringing.
