Any regain in anyone?

I know how everyone is feeling. I am very disapointed in myself. I never reached my goal, I started at 301 and got down to 207 and just stopped losing. Now I am at 214 and I have tried different diets to lose some more but nothing is working. I am really upset I couldn't even lose 100 pounds. What do I do now? I am just feeling sorry for myself. and I think about food all the time. I am a nighttime eater and that is where I have the most problem. I seem to want to eat all the time. Help!!!!!!!!!
