In over your head

Ever feel like you've been in over your head at a job? You met all the qualifications, had a fine interview, but when you hit the job, you didn't understand a thing? I'll fill you in when I'm not at work (though my home connection is down right now).
I'm like that right now. Gives me a headache. No way am I going back to retail, though.
Anyone else?
