I don't have answers, but am definitely in the same boat as you are. My HA is out of control right now, and I'm dealing with that two-pronged focus of trying to find out what's wrong (and what isn't!) and how to treat it, as well as dealing with the horrible anixety that comes alone with not knowing what's going on with my body.
I do have ativan to take regularly now, but I haven't started yet, just because so many other things are up in the air. My CBT therapist and I are going to have to focus more directly on HA in our next many meetings, but so far, that's premature too.
Good luck to you!
