I can totally relate - the shaking has always been the worst for me. Sometimes I can't even hold a pen without having shaky writing in front of some people, and I hate when they stare at whatever I'm writing intently because it takes all my energy to hold it together. People just stare at me like I'm crazy if they notice me shaking...which makes me shake more. Then it feels like my brain goes on autopilot in that moment and can't come back to the present until the situation is over.
I don't turn red because I'm tan but my face can't hide the fact that I'm uncomfortable because I'm so easy to read. Never learned how to hide my feelings like other people seem to do with ease. If I feel even slightly uncomfortable, many people can tell - I don't know how but they can!
