I start from (and return to) this Index page, where you see new activity:
http://forum.lowcarber.org/index.php?
Easy to see the main sub-forum headings there. You could start new posts where appropriate. If it is specifically Bernstein diet related, or your BG readings, the Diabetes forum under Health. How to LC in general can end up under Newbie Questions, Atkins, or General LC. Then there is the Tips and Stalls advice I linked. Definitely not perfect, but this forum welcomes all versions of LC, it is not just for one diet. Look around all of them and maybe read back through a page of posts in forums of interest. Great information buried in all those sub-forums. If searching for a topic, use Advanced Search..regular box is useless.
And the Recipes are all indexed, find one in the sticky at top, and it is linked to the post. That is organized well!
And in your account settings, be sure you get daily alerts to any posts in any thread. If you subscribe to a thread like the one on dairy, there can be weeks without activity, then an update, so you don't lose track if interested in various forums.
Glad you are working with PT. We think we are doing something healthy for ourselves, elliptical for you, yoga for me, when we are just aggravating the situation.
Long answer to where you get calcium without dairy:

My suggestion for dairy follows any Paleo elimination diet...remove all dairy entirely one month and then challenge it back very carefully. Whole30 linked above, or Chris Kresser's Your Personal Paleo Code, etc have the details how to do it correctly.
