Can’t get motivated!

I keep telling myself that I’m going to start eating healthy and exercising. But then I see all the snacks in the house (for my 2 kids and husband, so I can’t not buy them), and I eat them instead of healthy foods. And as for exercise, I think what’s the point when I’m eating unhealthy?

I feel like when I do eat healthy, I’m always hungry, and craving fatty foods!

I’m really wanting to try for a baby, but this lifestyle is no good for me to even get pregnant.

Help!
