A 21-year-old woman attends the GP. She has been feeling extremely anxious over the past few weeks, despite saying she “has little to worry about”. Her heart has felt like it is racing, she has been sweating more than normal – including through the night – and her hands feel shaky. She has not been sleeping well and has also lost half a stone in weight in this time, even though she has been eating as normal. She is wearing a vest top despite it being early February.
