Take a deep breath, count to ten, another deep breath. Sorry you're having a bad day.
I know it's difficult living with other people that don't have the same focus to change eating habits. But the bottom line is, you have to start focusing on you. Talk to your DH on how important it is for you to lose weight and eat more healthful food. If he doesn't listen, then forget him and focus on you. Your DD is still young, so she'll eat whatever you give her.
I live in a house with 4 other adults who don't take food that seriously. They eat what they want to eat and that's that. The other day they ordered pizza. I sat down at the table right in front of the boxes of pizza, and I ate a veggie wrap. Didn't touch the pizza at all, not a slice, not even a bite. I was so proud of myself. All I keep thinking now is "my health, my health, my health". Of course I have my weak moments too. If it's too much for me, I don't go near the food until it's gone. I'll go on the computer, or play a video game, or watch TV.
Good luck to you, I hope things get better.
