Is it normal that when i'm depressed all i really wanna do is cook?

When I'm feeling the most frustrated, hopeless, and depressed most of my usual distractions fail me. I don't want to watch TV or read or talk. The only thing I can think of to do to escape misery is to cook. It's the only thing I can focus on long enough to complete it. It's a pretty strong urge, and I usually want to make something really complicated that takes a long time. The strange thing is, I have TONS of hobbies, but I'm not interested in any of them when I'm depressed except cooking. Why cooking? It's not because I'm hungry. If I was just bored or hungry, I'd just eat some grapes or something.

My theory is that it has to do with selflessness. I tend to feel a lot of guilt when I'm depressed. I think a lot about other people suffering. Sometimes I feel like I want to volunteer more or that I don't give to enough charities. I think to placate my urge to help others when I feel helpless in aiding myself, I tend to try to think of something I can do for my family, and the only thing I can do well, that I know for sure they'll all appreciate, is cooking. I like to surprise them with a 3 or 4 course meal and to see how grateful they seem. IIN?
