Marley, Momma, and Becky. The best part about coming here is that you meet so many other people who have been through what you are going through.
About missing your pizza, I think that we all go through a "food mourning" kind of stage where we do miss our old food and old lifestyle. I can promise you though, as you continue to shed pounds, you will learn to love eating the good stuff, and your body will crave it. When people you know start commenting on your WL and how great you look, you will be even more encouraged to keep on going.
About self esteem, I have really been there on that one. When I was at my highest, somehow I had managed to forget about myself. I had 3 little kids, a job that was taking over my life, and I did not care anymore. I never put on makeup, did much with my hair, wore jewelry, nothing. I never bought new clothes. My mom would buy me clothes for Christmas and my birthday, that was about it. And they were mom clothes. Turns out, I don't really like mom clothes. I really like to buy my clothes in the Jrs dept, show a little cleavage and a little more skin, and look younger. When I started LAWL, I found this forum. One of the members suggested finding non food rewards to celebrate milestones in your weight loss journey. Suddenly, I was buying stuff for myself, a new feeling for me. I have used rewards like clothes, jewelry, shoes (I have a major ebay shoe addiction now), and makeup to cheer myself on. When I broke the 200 lb marker, I bought a new comforter for my bed. A ridiculously expensive one that I would have never purchased otherwise. I snuggled up in that blanket just last night when I went to bed, and it serves as a constant reminder to me. Anyway, point being, the more weight I lost, the better I felt most physically and emotionally, and it really shows. I am a total clothes whore now, I always do my hair and makeup, and I feel great about myself. Keep going, keep losing, keep eating right and drinking that water. You are worth it, and somewhere in there is the person that you used to be, just waiting to emerge and help you take your life back. I know that it can be done, because I have seen so many here do it. Just remember this one thing: You deserve to feel great, look great, and have good health. No one can do this for you, but you can definitely do this for yourself. Keep close to the forum, as you will need reminders and support from time to time. Your support and help will be needed by others on here as well. Have a great day!!!
