Can't stop eating and tired!

I know the whole eating for two thing is a myth, but I'm hungry constantly. I try drinking water and eating all those foods they say are good for you and curb cravings, but it doesn't work. I'm tired all the time despite the three supplements I'm taking. Is it just me? I want to be one of those girls taking pictures during their workouts and you can barely tell they are pregnant. Sadly this is not the case. I can barely stay awake at work and eat all day 😩.
