i have social anxiety and today while paying for my groceries, i gave the wrong amount of money to the cashier multiple times in a row.
i deal with anxiety myself, so i know not thinking about it is easier said than done. take care of yourself and try to find a good distraction to get your mind off it!
i apologized profusely. probably enough to make myself seem even more awkward than i already seemed. ugh, i need to stop thinking about it.
