I feel like my hubby doesn't appreciate me

My hubby has been laid off for the winter and I know he misses work. He's not a dead beat or anything. He's a very hard working man. Sometimes, I feel like he doesn't appreciate me. I know words speak louder than words. It's just that I go to work, I pick up the kids, and I make dinner. I also clean the house and do the grocery shopping. I give him a break because I know he's depressed about not being able to work. There's no work here if your wondering. Is it all in my head? I would just like him to say that he appreciates me once in a while. I know this doesn't matter, but I'm a step parent. I pick the picks up from their mothers and take them to activities or our house. Am I crazy?
