I get out of breath when blinking, am I obese?

I get very winded when watching tv and blinking, I am not sure if I should be considered obese or not. I eat around 2 large pizzas at a serving tt I drink a diet coke and then have a drywall sunday with whip cream (low fat) and afterwards I watch tv and start losing my breath after 3 blinks. Someone help me find an answer, also I have a gf and we are waiting to get married before we have but she keeps catching me in the act rubbing my on warm country style beef ribs and then I eat them. Is there something wrong with me?
