I understand the anxiety. Having a new company taking over our office, we are always being "reviewed" like they are trying to find us messing up. Go to work and be yourself. All you can do is your personal best and that is good enough. I became so obviously sick and upset at work yesterday that the office manager is making me take the rest of this week off. I constantly worry about losing my job. Know how you feel. Hang in there. Let us know how things go.
