Over the last month, I've watched my weight drop significantly, with no change in diet, working a desk job and no increase in anxiety. I am booking a drs appointment tomorrow but am absolutely terrified there's something seriously wrong with me. On 20th November I weighed 180lbs exactly. Today I weigh 170.7lbs. I'm 32, 5ft9, and currently having what feels like a mild panic attack. I'm so anxious it's something awful.
