Hi Karenja,
You sound so much more calm in your post.

I was on a couple of hrts last year and had galloping anxiety, palps, and other weird stuff that just made the anxiety much worse.
I saw a psychotherapist for many months last year and really turned a corners when, in consolation with a great Nurse Practitioner, I decided to stop hrt. It took about 9 weeks to work it's way out my system but, like you, I felt so much better.
I take 1000mg starflower every day and have done long before peri reared its ugly head... I get breast cysts which require draining and my breast consultant advised me to take it... Keeps them under control.
I also take Menopace Extra and vit c, three for two in Boots and Sainsburys. So far any flushes I get are mild and manageable.
The psychotherapist was lovely. She'd been through similar when going through the menopause herself. She taught me so much about myself and gave me brilliant coping strategies for when anxiety comes out of nowhere.
I also do yoga, brisk walking, and try to do mindful meditation - it all helps.
Good luck with the ECG - getting out for a walk and enjoying the elements, rain, snow, sun etc is good food for the soul.
