Ready for a new start

I was on here from 2010 to 2012 and I lost a significant amount of weight and was back down to a healthy, normal weight. I was happy and comfortable and after I ran the Spartan Race in 2012, I told myself I needed a break and then I'd be back. Yeah, it didn't happen. I gained ALL the weight back that I lost and then some, and I feel so horrible about myself.

As of January 2, I am starting new. I already have goals set. I just need new motivation and last time, I was able to find perfect motivation here on MFP. Anyone willing to kick my butt? :)
