Encouragement

Hello, I need a boost to encourage me to keep up the good work; I have been on this diet since January 19, 2015 and I finally lost my first 10 lbs. as of 3/12/2015. It seems like it took a very long time to lose those 10 lbs. In the past, I could drop this much in one week. I'm shedding very slow and starting to become discourage. I have 68 more pounds to go by July 2015. Please help!
