You have a job that you are totally unqualified for and not cut out for . The office hates you. You do...?

I thought it was at least partially a design job, but it is a detail oriented managerial position working with non-creative people in a catty and conservative office full of bitchy office ladies. I am totally miserable and this job makes me feel like an idiot every part of every day. I don't like moving around from job to job, but clearly I need to do something. What would a good exit strategy be? I don't want to screw over the company, but I am screwing over myself by leaving with no option and would never just immediately leave without tying things up.
