Attachment to your T is normal but scary. I spent two months perceiving mine as cold and uncaring (when he's really not!) as I was afraid to attach so it was easier to believe he hated me.

Definitely clarify boundaries as these can vary in some areas eg if it's okay to call, text or email. But also could you try to tell your T you are afraid of feeling rejected. I do agree with anilam that this approach could make you feel rejected, but of course everything goes through our own internal distortion filters and maybe what she meant was not to be afraid as she will guide you as you go along. I'm not saying I don't believe you, just that it's always worth asking yourself if that's really how they meant it.
