Can't say what is going on with her, but she should at least be gentle with you. Sounds a bit gruff to me. My advice is to call other people just to talk. Get to know others and see if you like one of them more.
There are all kinds of people in AA. It took me awhile to realize they aren't all saints, they have issues too, and once I found the right sponsor, it made a huge difference for me. However, I had several along the way, and some were just awful. So stay in touch with the people you can relate to, and keep talking/sharing.
