Welcome, mrsnacho! Love your name.

I'm very sorry to hear about your diagnosis, but that's good news that the doctors think they caught it in time.

Did you get a referral to this T (therapist)? Is this T supposed to be knowledgeable in health issues? I think that would put me off, too. In fact, I had a similar experience - my first visit to a T (not the one I have now), I was saying how badly I wanted to lose weight, and she started giving me advice that just really turned me off - asking me how I eat, if I'd done this exercise, if I'd tried this or that. The point was that she wasn't listening to me, or at least I certainly didn't feel heard. Needless to say, I didn't go back to that T!

Can you talk to this T about how you didn't care for her going into authoritative mode on you? If you think that won't do any good, or this T won't change, maybe this isn't the right T for you.

Good luck!
