I have a f2f sponsor. I email her daily with my food and a general plan for the next day (nothing specific, since that's a trigger for me, but an idea like "get 5-7 veggies and fruits" or something). She does not comment on my food. But she's always good for positive comments, etc...
I see her at least once a week at a f2f meeting and we usually chat a few minutes afterwards. We meet when I finish my step work. I read my answer to something, then she reads hers from when she completed the step, and we go back and forth like that.
I think it's harder to find an online sponsor to connect with, but it definitely can be done! If you're unhappy with what's going on so for, send out an email. Put your feelings down (in a nice way
) and ask your sponsor for some input. What you need may be different from what she gives as a sponsor. It's best to know now.
Good luck!
