Hi Fruit loop, yes I too am in the anxiety club in a big way. I had it first perimenopausally - just came out of nowhere and exactly as you describe, a horrible physical sensation (being on top of a roller coaster is a good description). It seemed to gradually improve then but never quite went away. Then 2 years ago, still before I hit the menopause proper, I had chemotherapy for breast cancer and that sent me into sudden menopause overnight. I started on estrogen-only HRT for a few months to get the level up from practically zero, and it helped with the depression a lot. Then started Utrogestan and wham, overnight I was hit with massive anxiety, always first thing in the morning and lasting for several hours, and nothing would shift it, regardless of whether I was taking utrogestan or not. So now, nearly a year later, I'm still struggling with massive anxiety, had to change GPs to get it taken seriously as a menopausal symptom, and am only coping by taking a large dose of diazepam every morning. So you're not alone, I wish I had a solution to offer but I haven't found it yet, will let you know....x
