I found this website last week.
I suppose if you have a sensitive disposition don't click on the link. / trigger warning. The picture at the top of the page isn't nice but very accurately depicts how I felt yesterday when amongst others and how I've felt today. After my comment on another thread about it - today, I'm honestly not sure if it was worth it. I've been in a heightened state all day and it hasn't been nice. It's not going to miraculously disappear.
The article is also useful about sensory difficulties / trauma which can build up.
