Is everyone on a diet?

So, let me just start out by saying....today is a new day! I have been struggling with dieting for 5 straight months now. I know, I know.....some of you are saying....big deal....I've been struggling for years. The truth is, it's been on my mind, and at my fingertips for 5 straight months. For some reason, I just can't get a handle on it? I now have to journal my eating habits. I can't seem to keep sugar and sweets completely out of my life, and I am very discouraged that I only have 3 months until swim suit season (which by the way, won't be happening unless I lose 30) I have people in my life that seem to be losing weight at the drop of a hat. What am I doing wrong? I just had to vent. How's everyone doing?
