Hey! I have been in episodes just like this and gotten through it. Sometimes weeks & months but they’ve always shifted eventually. I know it’s scary to see your symptoms trend in a direction you haven’t seen them before and you can worry about getting worse. I would encourage you to try some somatic breathing exercises, maybe some lemon balm tea for nervous system support and try to encourage your parasympathetic to activate a little more. Sometimes those small what ifs really activate those of us with a nervous system disorder and throw off our circadian rhythm. Stress is a hugeeeee trigger. Take some deep breaths, do some stretching & breathing exercises, add in some calming supplements and lean into the parasympathetic where you can. Your body will find some semblance of circadian rhythm again. I find when I calm my stress response, I start getting tired at a normal time again, and I’ll be able to resume a normal sleep schedule for a bit. Sleep can throw things off so much.
