I always feel strange during Winter... paranoid and a bit vacant, could it be SAD?

I know I react badly to lack of sunlight but it effects me in strange way, I feel generally ill, agitated, depressed and get quite paranoid that DH is having affairs (not that I have ever amitted this one!) He gives me no reason to by the way. Could this all be related to SAD?

I don't know but I know that when the weather is grey or rainy I feel a bit more down than I would otherwise.
