And do you have any advice for me, a family member, of someone who has it.
That someone is my mum who too suffers from extreme health anxiety.
She has it in episodes but when she has a episode it triggers her anxiety and she doesn't mentally get over it for a long time.
She is medicated and receiving support. It what can I do or research to help? Do certain foods or diets help? Anything to help the heart rate return to normal?
Just after experience really!
