Butterfly - - Shame on your friend! I too am going with this where my choice to have a better life has created an issue with my best friend. While I can sympathize with her challenges about her own weight, why would you bring me down and make me feel bad about my decision? The instant - "what about me?" filled her mind and she actually had the nerve to tell me well, "great, I'll be the only fat one left in the family." (She's my best friend and cousin.)
For years I have been heavier and can't stay fat because her personal image will be different now. It's sad and definitely wasn't the reaction I had hoped for. All too familiar with me - don't feel bad! We are fortunate to see that life style changes are necessary and we're bettering our lives. We cannot stay fat to save the feelings of other people.
Congrats on your decision and chin up! Your friend will either have to come around and deal with it or lose a great friendship with you. HER LOSS!
