Can you try telling your T that you need some "outside" reassurance? Or just ask directly for her reassurance?

When I've been in similar situations with my T, where she doesn't immediately give me the reassurance I need, I've usually just blurted out "I really need some reassurances from you right now." Usually, my T will give a small smile, say okay, and then offer her thoughts and support. She typically won't do it unless I ask, though.
