I understand your feelings. I worked for years with a boss I loved, but now the one I work for is now is intimidating. I would definitly feel like you if he summed me to his office. I, so, feel your anxiety just thinking about it. Why don't you try some breathing excercises to help calm the anxiety. Or put on some relaxing music. Try to engage yourself in something you like to do. Hope some I said helps, but I know if you are like me you'll worry anyway. take care of yourself.
