Good luck, I'm sorry you had that bad experience, but it sounds like you're trying to take what happened and turn it into a positive. Trust yourself- if you think you need to go to rehab, do it. And if you want a new sponsor and you think that is best for you, find a new sponsor.

It sounds good that you're already looking into other meetings too. It's nice to have a place you feel comfortable, but might also be nice to widen your horizons. Best of luck.
