The sensory sensitivity is unreal

I’ve always had sensory issues, my entire life, and severe ones. But my LC symptoms and sensory issues worsen each other mutually, the severe pressure in my head and sinuses gets a million times worse when I feel overstimulated and it doesn’t make any sense to me!!!!

I had panic and started uncontrollably sobbing in a semi public setting the other day because people were having quiet chill conversations around me and it was too much sensory stimulation when my symptoms were that bad, and in turn my head pressure got even worse and I almost ripped my hair out in public. It’s terrible because your emotions are on raging fire while your body is in a state of severe poison like exhaustion, cognitive dysfunction, and pain. I hate long covid it’s so fucking unbearable the discomfort I’m always in, I cannot fucking believe we’ve woken up every day and had to feel it again and again and again.

Anyways, I’ve been getting worse lately due to taking a break from nicotine patches and this has been happening more and more. I don’t mind looking crazy but it is a torturous feeling and makes me certain this is at least in part nervous system related.

Does anyone experience this and figure out how to calm your nervous system down on demand?
