Not New: Here again

My name is Laura. I have been overweight since I was Middle School and into High School and now into my adult life. On January 1, 2009 I joined this site and I proceeded to lose 52 pounds However, I was in a car accident on May 29, 2009 and I let that stress me out and I let life get in the way and I have gained all the weight back and 3 pounds more. I have been having so many health problems lately and I went to the doctor today and he told me that my Liver Enzymes are a little high and that can be caused by a Fatty Liver and a Fatty Liver is the result of being overweight, or it's a anti inflammatory med that I was on that was causing the Liver Enzymes to be high. Now I don't really know if I have a Fatty Liver or not and neither does the doctor but it was embarrassing hearing that and I am ashamed for letting myself gain all the weight I had lost back and 3 more pounds, but I won't let embarrassment keep me from coming back to this site and trying again and this time I am going to succeed if it takes me forever. I am so sick of being this way. I am back and determined to do it this time. I have 2 little kids that are depending on me to be around a long time.
