My issue is that I don't actually have enough of a connection to my body, thoughts and feelings
Do you need those, though?
I think deciding how you want to be treated, & insisting on it to the greatest measure you can do, does not depend on feelings, or how connected you are to yourself, or your thoughts. Just that you decided you want to be treated X way... & that is it. How you go about enforcing that decision is, surely, going to take bit of a practice, may be influenced by all of those factors, but is not dependent on them, either.
