I know how you feel. But I have learned this, people are too worried about YOU looking at THEM, and how THEY look than analyzing you and your flaws

I weighed 170 and was in the best shape of my life, then i gained almost 100 lbs after getting pregnant (i was put on bed-rest) and all i could keep down was bread and milk (super fattening+carbs==eww) and now weigh about 240. So, i definitely understand not wanting to be looked at. I don't look like a mutant, but I feel like i should definitely look better than I do. I have a treadmill, and am making an honest effort at getting into shape.
You have the gym membership, you're already starting out on the right foot.
I'm sure your husband isnt going to look at you and saw "eww that is nasty-she is trying to get healthy", maybe he is worried about the same thing--you looking at him?
