Feelings. Feelings are holding you back. I also realized this recently. When I first lost my weight I told my feelings to shut up. Just like going to work every day I don't let my feelings stop me. That would be nuts. I just get up, go to work, even though I don't like it. Because I have no choice. You have to look at weight loss that way too.
Your going to get up, eat less, and that is all there is to it. Like paying bills or cleaning the litter box. Your just going to do it. You don't have to feel like it -- you don't need motivation, you are just going to do it.
