If it's that bad then I'm sure he'll have noticed by now. In which case he's been kind enough to not say anything until you're ready.
If he hasn't noticed, he's your husband and he married you because he loves you. I'm sure he'll be happy you've identified your problem and that you're doing something about it!
He'll only want to help you through it and it will feel like such a weight off your chest once you've been open with him.
Good luck xx
