I think I've an idea what you mean--though certainly don't claim to be an expert.

Do you think it's possible that you've internalized your attachment to your T? Yes, she's still a source of comfort, and, yes, you still want to see her--but you're secure enough in your attachment to not need to think about her or e-mail her when she's not around. I think that would be a good thing.

To draw an ugly comparison--I love my mom. I'm attached to her and want to see her. But I don't think about her all the time or e-mail her everyday. I can carry around what she represents---love, importance, etc---without needing her physical presence.

Maybe your uncertainty about therapy is just the desire to maintain and check up on that internalized bond (and what it represents) in the absence of more pressing concerns?
