i've been terrified by episodes of extreme dizziness in recent months., but I've kept them to myself. because I assumed they were a symptom of hjigh blood pressure. The other day, I lost my footing at a tube station and went into a horrible brain-spin free fall. Fortunately, there was a doctor just next to me, and a couple of lovely tube employees. The doctor [who'd just come off a night shift at UCL] was amazing. The tube employees wanted me to have a cup of tea. They were all so lovely and kind.
