Parents are (sometimes unfortunately) just people too, and they make mistakes or are just crappy people. Your dad has no right to call you obese. Not only is it not nice, it's most likely partly his fault.
We learn our eating habits from our parents. It's probable that you got your emotional eating baggage from them. If you eat when you're stressed, it's because you saw them doing it. So take his comments with a grain of salt. Not saying it won't hurt, but you need to know that he's fallible.
Working in a grocery store is perfect. It's not like it's a pizza place or a chocolate factory. Now that would be hard. But you've got fresh veggies, and seafood, and everything else you need to make Atkins a success.
There's a saying you'll see around here that might help - nothing tastes as good as thin feels. Before you put anything in your mouth, ask yourself if it's worth it. Worth not losing for 2 days. Worth your self respect. Worth the depression. Are you even going to remember what it tasted like in 2 days?
Take each meal as it comes. If you make a mistake, just try again at the next meal. Pretty soon, you'll have several days done right. And before you know it, you'll have several weeks. Then in no time, you'll be at goal.
If you get discouraged, come here. Skip the negativity at home and school and hang here, where you're supported. You don't need people dragging you down - you're too good for that.
