Why am I not moving up at my job?

I've been employed at my job for 6 years now , missed a handful of times , always on time , and get along with all my coworkers. The problem is I've asked multiple times to move up the ladder and everytime have been given an exuse why they won't do it. I would not be as salty about this but everyone else who I work with has moved up and I've been there the longest!! I feel like the black sheep. 
 Question #1. Am just feeling sorry for myself and should I get over it.

Question #2 How would you feel or deal with this ?
Thanks
