I'm not apologising for her not telling me theAs I said previously, make the appointment with the nurse & start with a clean slate. It may even be an idea to apologise if you were perceived as being confrontational, even if you know you weren’t, just to help reset the relationship. Unfortunately we need these people on side, & that sometimes requires some tongue biting!
Then have the same discussion you just posted, with an emphasis on your desire to make lifestyle changes & seeking support with that. When I was first diagnosed I was offered discounted membership of the local Council gym. Well that’s not strictly true, I saw it advertised in the waiting room but had to ask for it.
Also ask about educational courses & support groups.
If you haven’t already, start wading through the info on the main site, maybe making some notes of key relevant bits as you go. You don’t need to take it all in at once & it sounds like you have a decent handle on what’s required anyway.
contraindications and then telling me I was wrong. These people are not gods.
