Life is an utter disappointment

That I often think about whether it's worth continuing with this lunacy that is my life. I am utterly disappointed in my daughter and my wife. It was my birthday, and they couldn't keep it together long enough to make it even to the cake and song, and I am now at birthday+1 and my gifts are still wrapped in the dining room and we've been picking at the cake. I wish them dead, and I wish myself dead, but am too dead already inside to do anything about it. I hate my life. I sacrificed my health to save people in 9/11 and spend my days trying to make sure kids have the healthcare they need...why must my life be so awful? Why am I being punished? I just wish this would all go away.
