I'm sorry to hear that you have had such a rough experience.
The first thing that I would recommend is to Google the AA Intergroup for your county or state. The local intergroups around me have volunteers manning the phones that are willing to chat, so The ones closest to you might have the same. After giving you an ear for a while, they will be able to give you a list of meetings where you can find a new sponsor.
Your sponsor probably handled the situation the best she knew how, but the reality is that it was not the right approach for you. Because of this, you no longer trust her. You can't have a sponsor/sponsee relationship, IMO, with someone that you don't trust.
Google up an intergroup list and get on the phone as fast as you can. Channel that energy into a way to help you.
Good luck, hon.
Addendum:
Here is a site with an intergroup list in England:
