Here's some CC for you, Amber (I know you're reading):
You fail over and over again because you have absolutely no self control. You get yourself all motivated and wake up the next day with cravings for Mexican and Chinese, and then you indulge while saying to yourself "one more time won't hurt, I'll get on track again tomorrow," but tomorrow never comes. It's an endless cycle of gluttony. You don't know what you're doing. Even a child knows to eat fruit and veggies and you'll be healthy; It's common knowledge. You need professional help - a nutritionist, a therapist, a GP, SOMETHING. You have severe, deep rooted mental issues that are causing you to over indulge. You are at the point of no return, and you cannot do this alone.
So keep crying on YouTube to the haters that you know everything, and that you're always right. What do we know, anyway? It's not like some of the people who watch you have lost hundreds of pounds, possibly study mental health, or actually know what they're talking about, because Amber is always right and Amber knows how to take care of herself. Obviously, you don't, because you wouldn't be steadily approaching 600lbs if you did.
I give her a week before she's back to counting calories, WW, or some other diet plan. She will never stick to anything until she gets some serious help.
