Numbing is something that we do to protect ourselves. You are feeling anxious about starting a new job, so numbing is a way of putting aside the anxious feelings so you can begin the job like you want to do.

Try not to add the stress that comes from wanting others to understand what it's like for you. I think we forget how stressful things like beginning a new job can be once we are through it. Set aside their not being able to understand for now.

New jobs are anxiety provoking, but the good thing to remember is that it is the newness and the unknown that we are anxious about. It won't be long before the new job will be something familiar to you and then your fears/anxiety will ease and you'll feel so much better.

Good luck on your first day of your new adventure!
