I've been struggling lately with that. The physical symptoms have become worse since a crisis about 7 months ago and another around 2 weeks ago. They prescribed me diazepam, which really helped but made me a bit useless and dazed. I didn't mind it though, I liked the sedative effect. It was bliss for a while. But it's considered too dangerous at the moment because of my low weight and blood pressure. I've found weighted blankets help me, and trying to keep my blood sugar levels balanced, using grounding techniques like focusing on sensory things that won't trigger it further. I use my dog's blanket and remember his strong, steady heartbeat. Mindfulness and focusing on my breathing... running out of ideas these days though. Nothing works as well as that diazepam did on me. But they're hesistant to give me any more benzos for a while. I sleep a lot too. I try to curl up under my heavy duvet and wait for it to pass. Getting harder in the summer. It's that rapid heart rate that puts me most at risk at the moment. I've been severely underweight most my life and they believe that this loss of body fat and loss of muscle may have affected my heart. Definitely the anxiety that's causing all this. I first started having it when I was 3 and it caused sudden extreme weight loss. So I also pass out a lot and have low blood pressure and issues with my resting heart rate. The crisis I had 7 months ago when my dog died caused me to become hypervigilant, develop severe tics, dissosiation and auditory and visual hallucinations, the hyperventilation caused hypoglycaemia (severe blood sugar drop). Hypoglycaemia is usually only something that diabetics get, so we were surprised. I live in fear of another one of those severe episodes all the time.
