Nal- You can do this! My advice to you is to make make a list of the reasons you want to lose weight and post it where you will see it often. Add some pictures of you when you were thin, clothes that you want to wear, etc. Also, I think that it really helps to set up some rewards. For instance, a new shirt after 10 lbs., and haircut and color after 20, mani and pedi after 30, massage after 40, etc. Make it work for you. But most of all, be nice to yourself. You deserve to be at your ideal weight. You can definitely get yourself there.
