Needing that Motivation to Reach My Goal

I can definitely say it is sad to see myself not be able to fit into shorts or shirts that I've previously worn within the year prior. I'm just starting to use MFP so I am hoping I am able to reach my goal into losing weight and becoming more confident in myself. I've done it before but starting now I'm not going to drink any soda whatsoever and I'm trying to limit myself on sweet caffeinated drinks. I'm trying to be able to look great for my friend's wedding in August but also be able to walk confidently without my shirt in May for Las Vegas with friends. It's hard to stay compliant but I'm going to try as hard as I can to stay motivated and strict on what I need to do. Thanks for the support!!
