....I only know how to sulk, self-hate, and experience short bouts of "determination."
When I try to step back and think what is really bothering me, what is really holding me back...I think it may seem so daunting at this point. About 115 pounds to lose.
So instead of doing little things to illicit bigger changes, I eat, and cry, and hate myself, and avoid thinking about how much I'm putting my health at risk.
The last time I ate was almost six hours ago and I still feel full. My boyfriend and I each ate a medium pizza from Domino's--at my urging. I ordered it. I paid for it. Because I wanted it.
He's gained weight since being with me and I hate feeling responsible.
I hate feeling full six hours after eating. This is not natural. And I feel my body being strained on a daily basis--my poor organs being squished from all the belly fat, my lungs not able to expand enough to get a full breath because of the fat, my chins resting upon themselves if I pull my head too far into my neck. I'm aware all the time about how unhappy it makes me, the desire to lose weight is ever-present.
Yet my actions go against this desire.
I don't know where to start--how to "give a care" anymore.
Any inspiration?

i also think you should see your doctor, if you describe your feelings to her/him, they will recognize the signs of depression. I'm not a pill-pusher but I feel my soul has been saved by proper medication. As a wonderful side effect, I also got back my 'give a damn' attitude, so I was able to stick to better eating and working out almost every day.
