I am scared of feeling stupid a lot. at work, in stores, when i order food.....SOOO many places. It sucks.

I am trying to practice this:
Remember my assumption (construction, conviction) for instance: "I am going to annoy them" and WITH THAT in mind go into the store. With the fear and everything.

After you are done ask yourself if most people there reacted in away that showed annoyance or not?
Try to recall what you thought before you went into the store, all your fears, and now see which were justified and which were not. Next time you will go into a store remember your last experience. Always pay attention to the way you feel before you go in - and after you get out - examine what happened, what you exactly dear, if what you fear the most happened - if yes- how are you doing now?
