Hi Jenlou,
I was afraid before my first Alanon meeting, but several people attended and made me feel comfortable. You don't have to share if you don't want to, you can just listen to others. It is amazing how healing it is to listen to others. Good luck and let us know how it goes. Oh one more thing all meetings are not exactly alike so try to go to several if you can and see which one fits the best. Take good care....
