Nole is bang on the money my friend. Your education could be doing you more harm in a certain way. I bet you will be hard pressed to find an immediate supervisor who can match your academic level, and subsequently are getting passed over for fear of showing them up and eventually passing them up.

What Nole stated in his first post about them believing you will leave once something better floats by. The government is fickle, and they love education over experience in certain situations. I am not knocking you at all, rather impressed actually with your age and amount of education. Heck in N.C. we have 24 year old highschoolers! j/k
Get on USAJOBS and look above support positions, your education can help you at least land an interview.
WHIPPERSNAPPER!!!
