I think that no matter how accomplished, self-confident, and strong a person is, there is something about therapy that makes us, at times, go back to being a baby or a child. It doesn't mean we're not capable and confident in our "real life". I think it's perfectly normal for you to react the way you are, especially in light of this quick termination. It's okay to let T see your feelings. Leaving your T IS a loss; you're not making it up. Did you see her yet today? I really hope you can tell her, without holding back, that you need to know what her rules are for contact post-therapy, and to tell her how you feel, as you posted here.
