An article by Lorna Thorpe - Did anxiety cause my heart attack? - appeared in last Friday's Guardian. Since her mid-20s, Lorna Thorpe has suffered crippling panic attacks. Now, after a cardiac arrest at 50, she lives in fear that her worrying could kill her. As well as re-visiting this life-shattering experience in the her article, she has written about it in a sequence of poems in her first full-length collection, A Ghost in My House, published by Arc earlier this year.
