Fallen off the wagon

Options
I've been obsessive about logging everything on MFP but my weight loss stalled and so did my motivation. I've been using it but not diligently and not eating the best. I got on the scale today and I've gained 7 pounds. I hate myself for allowing it to happen and frustrated because I feel like I'm never going to reach my goal of losing 75 pounds and being the weight I was when I got married because I hit 65 pounds and nothing I did made it budge for months, then I lost 1 more pound and again nothing. I feel ashamed that I worked so hard and threw the results away. Anyone else go through this?
