Frustrated

I haven't really lost any weight in the last few months. Partly that was because I didn't stick to eating as healthy as I should have during the holidays, so I get not losing any weight. I didn't gain any either, so I was happy. In January I started eating better and exercising. I haven't lost a pound. As a matter of fact, I've actually gained a little. I'm frustrated and I don't know what else I can do. Last year I lost 40 pounds, so my goal was to lose another 20 this year and just maintain it. At this rate, it's never going to happen. Ugh.
