Looking for a accountability friend

I'm really struggling to stay on track. I'm getting married May 2014 and have a lot to lose by then. I'm 26 and I work 2 jobs and I'm also taking 2 classes online. I don't have a ton of time to work out but where I really struggle with my eating. I have a major sweet tooth, one of my jobs is working at my mom's gas station and temptation is all over the place. Is there anybody out there that could motivate me and check in on me? I would really appreciate it!
