I totally understand how you feel. Just today in the office, I had to deal with a situation where I am still learning how to do things.

I had to make two phone calls to find out information, and someone was in the room with me. I felt self-conscious, which complicated how my brain processes, and could not get the words to come out of my mouth. It was like my brain was screaming the words but I could not say them.

I feel so dumb sometimes because the simplest of tasks or words sometimes confuse me when I know they shouldn't.

However, I am fortunate enough to work where I have my own space, and am not bothered much so I can turn off the lights if needed and throw in the earplugs.

Hopefully these things will pass for all of us...
