How Do I Get This Off My Record

I have a "DUI" on my record that has caused a lot of problems in my life for the last 8 years. With getting jobs, and with traveling.

The thing is, I was arrested for DUI 8 years ago because I'm autistic and the officer thought I was "acting strange". He also found a bottle of Zoloft in my car which I was being prescribed at the time, and he told me that finding a bottle of pills in the car was enough to arrest me for DUI. I also failed to stand on one foot for long enough because I was working two jobs at the time, I was on my way to my early morning job, and I was exhausted. The only reason I got pulled over to begin with was that I briefly failed to maintain my lane while entering the highway and a cop happened to be behind me.

When I got to the police station I got a blood test that showed I had nothing in my system and I was not impared.

I had a very bad public defender who basically just told me I was guilty and convinced me that my only option was to plea my DUI charge down to reckless driving. Which is why it now says on my record "DUI amended to non fingerprintable offense"

I was told recently I can't get this restricted or expunged from my record because I took a plea deal. I can't believe this has to stay on my record since it's for such a dumb reason that was not my fault to begin with. I was innocent of the DUI because I was not driving while impaired and my blood test proved that.

Also wondering...would any lawyer out there be crazy enough to try to get me compensation for the pain and inconvenience this DUI charge has caused in my life, since it was a wrongful arrest to begin with and the county failed to provide me with reasonable legal representation? Could I possibly have a case?
