I've explained to my T that it's hard for me to talk and make eye contact at the same time, that verbalizing what I'm thinking takes so much mental energy I don't have a lot left over to stare her in the eye. I do try to make eye contact when she talks to me though. Body language is just another way they can "hear" us. She is probably pointing out what you do because part of their job is to mirror what we give out so we are fully listening to ourselves.

And I fidget like crazy in most situations, I can't sit still to save my life. I'm a kinesthetic learner. I wouldn't stress yourself too much. I talk with my hands too, but mostly when I'm hypomanic.
