In Need of Support

Here lately, I've just been really bummed with myself. I seem to have no motivation nor any self-dicipline at all. I feel like I'm always hungry, especially when I go home from work at night. I haven't lost any weight since I GAINED weight from Christmas. It was only five pounds (which was better than I expected), but now I can't seem to get rid of it. I know the carb-overload during Christmas is what helped trigger this. But what I don't understand is how I had the motivation and self-dicipline in the beginning to start losing weight, and now I don't! I can't get past that first week...you know, they say the first week's the hardest. I just don't know if I'm not eating the right foods...or what I'm doing wrong. I haven't had the energy to work out... That's my main problem, and I know that it's my fault. I've been seriously lazy! I just need the support and motivation. Tips and tricks some of you have used to curb the cravings, satisfy a hunger that seems nagging, etc.
