Sue Baker’s symptoms were as severe as they were strange. ‘It started with low-level nausea and sleeplessness which, over the course of a few months, became constant heart palpitations and physical sickness,’ says the 56-year-old mother-of-two, from Hampshire.
‘It got worse until I finally called a friend who was a nurse, and sobbed down the phone to her that I couldn’t go on. She rushed me to my GP and I sat in the waiting room having a full-blown panic attack. My heart was racing, my legs were trembling and I was rocking myself forward and backwards trying to breathe.’
