Kind of sad, really funny
It seems as if you took everything that makes a story sad, and combined it into one big package, and that makes the story about as sad as a guy getting hit in the face with a rake 20 times in a row. He's in pain, but it's just so ridiculous that you have to laugh. The dad is dead, the mom is dying, and when she dies, the kid has a heart attack. A heart attack out of love? Could you be any cornier? I'm really sorry, but this sucks.
