My only advice, from what I have witnessed in program, is to be willing to try anything. I know how scared you are, I remember like it was yesterday, but really, once you make the call, just like when you went to your first meeting, you will feel empowered. And please remember that individual programs vary widely. There is no 'diet' plan, no 'exercise' plan, no 'sponsor' rules. Sponsors give up to the level of their own experience, that is really all they have to work with. I am sure once you speak with her personally and discuss your own situations, you can reach a good starting point for you. Call tomorrow! If you wait, you are only delaying your own progress!!
I just turned 40 this year and recently a long term relationship ended. I moved to NC to be closer to my family and 'start over' yet again...my food plan has really been just to eat three meals a day, minimum snacks/dessert items...I have not really had a 'plan' for some time, just guidelines I know I need to stick with to maintain. Initially, for at least 5 years, I did as your sponsor, 3 meals/nothing in between...gradually reducing fat and reducing portion size. I am making a decision to be a vegetarian, (will still eat fish/seafood). So now I am eating Total breakfast cereal, soy milk and fruit for breakfast, usually will eat out for lunch, and dinner is a potluck of veggie/soy burger/fruit...I am single, so my habits leave a lot to be desired. That is part of the reason for going vegetarian, to eat a healthier diet overall...but again, I am just being willing to try and see where it leads me...
I will look forward to hearing from you again...
