Ditto to what Sammy said
You don't need to feel guilty, or apologize to anyone. This is a personal challenge for you and you alone. I do understand about the self-conscious aspect ... I used to hate going to stuff with DH's work people. Maybe I just feel better about myself because I've lost 1/2 the weight I want to, or maybe I've figured out that I'm still the same person, whether I weigh 200+ lbs or lower, but we've gone to a couple of functions this year and some guy friends of my DH have mentioned to him after the fact that I look great. Maybe I just needed the ego boost
your family will always love you. I don't think they'd be disappointed. I think the look you're seeing on their faces is what you are feeling about your own disappointment. Does that make sense? It's getting kinda late!
I'd take these feelings you're having and turn them into a positive spin. Make your guilt your starting point for doing 3 things in the coming week:
1) get out at least 3x next week for some type of exercise. A 30 minute stroll counts here !
2) when you go to reach for a snack, drink a big glass of water first. Wait 10 minutes. If you still want the snack, you probably ARE hungry and need to eat.
3) Take a small step towards portion control. If you go to put 2 big scoops of something on your plate, stop after 1 1/2 scoops instead.
Doing these 3 little things will actually make a huge difference over time, and you reap immediate benefits from doing so. Good luck my friend.
