I have a home group that I come and go from as I can. People come and go from these meetings all the time. You say that you are being made to feel guilty.....is that coming from someone in your group or from yourself?
Remember, we are all responsible for taking care of ourselves, and that includes the others in your group. If they are pressuring you for any reason, then it is probably not a good group dynamic to begin with.
Take good care of yourself, go to the meeting that benefits you the most.
