Holly, I agree, your stressing yourself before you get there. In your above you write a negative to then state you need to remember the positives. That says your not focused on the positives, but your in a lot of self doubt which is causing you stress. When you learn to believe in your positives and remove your self doubt, you will typically find you have much less or no stress surrounding an incident, event or situation. It really is about what you believe vs. what you just tell yourself. You must believe what your telling yourself, otherwise you fail before you begin.

Just remember, focus on you and enjoy the return to work. Don't fear it, enjoy that you are able to work, the interaction with others, the choice. They are all good things.
