How do I get rid of an "adjudication withheld" on my criminal record? Criminal Records, Expungement

I'm looking for a way to get my record expunged and /or sealed. I've talked to F.D.L.E but they say that I cannot because I was found guilty on possession of drug paraphernalia? Is there any other way that I can get rid of this "adjudication withheld" on my record? Below are my charges:

2 1 03/01/2006 893.13.6A-N EXP POSSESSION OF COCAINE LESS THAN 28 GRAMS 05/04/2006 ADJUDICATION WITHHELD
3 1 03/01/2006 893.147.1.B EXP USE OR POSSESSION OF DRUG PARAPHERNALIA 05/04/2006 GUILTY


This charge is 8 years old. I've been out of trouble since then and I'm trying to better myself. I want to go back to school to become a nurse but they said I can't because of my record. Is there any possible way someone can help me please!
