Not asking too much.
I email a list to my therapist based on all the other emails I have sent him throughout the week. I don't expect (or get) replies to any of the ones I send during the week, and they are thought of as "e-journaling". Before my appt, I send a brief bullet list of which emails I would like to discuss. It's usually all, but sometimes just a few. He does usually say Thank you. It takes 2 seconds, and I appreciate that he does it.
I totally understand why you feel the way you do. Maybe you need to spell it out for your T.
