Good call Bunny.
You're not the first person who had to part ways with their sponsor. You won't be the last. The schedule is big, there are a lot of meetings, and if you feel adventurous you could always try an NA one or two. Whatever works for you.
Find some people who have been around a long time who are obviously not crazy and relate your experience to them outside of a meeting context. It's been my experience that they will guide you in the right direction and give you some good advice
