How Do I Reject Promotion Offer?

Dear Experts, I've been working at the same company for about a year now and I don't enjoy myself as much as I used to. For the past two months I have been looking for a new job but haven't told anyone at work. Just the other day I was called into my manager's office where I thought I was going to be laid off (I was excited). To my surprise I was given a promotion! My manager gave me one week to make my decision. The fact of the matter is I don't want to continue working there even if I've earned promotion. I'm not happy at this company. How do I tell my manager I don't want this promotion? The company may think I'm crazy for not accepting, especially in this job market. I don't want anyone to find out or be suspicious of the fact I'm searching for a new job.
