Without a doubt, the best thing I tried was the NHS-approved Alpha Stim AID which is expensive to buy outright but can be tried for free for 30 days first. At first it felt ominously like a Black Mirror prop but soon became my go-to. This cranial electrotherapy stimulation device relieves symptoms of anxiety, insomnia and depression by transmitting an electrical waveform to your cells to help them regain equilibrium. You attach a clip to each ear and wear it around your neck for up to an hour each day. The results aren’t instant, but within a week I felt more in control – I slept better, I no longer woke feeling hollow with fear, and making it through a meal in a busy pub seemed increasingly palatable. I wore it every day for six weeks and now use it three or four times a week.
