Long and Complex question...?

I was arrested in 06 for criminal mischeif for throwing a beer bottle at a sign at a party I did not hit the sign but was forced into confession by the chief investigator who also smoked pot with the family pushing my arrest, anyways I was denied the right to my phone call and an attorney until after the police forced me to say that I did hit the sign or I would have to sit in jail for 3 days and the would make sure I faced serious jail time(i was scared and only 18 at the time) so I said what they told me to say. I was in and out of court for 15 months and they kept postponing my courtdate for another month, the my public defender who was friends with the judge and chief investigator told me to plead guilty though I was denying that I did anything illegal he said that if I did this the I would get 1-2 yrs probation max and have to pay for the sign and just so all this would finally be over I plead guilty and the judge gave me 5yrs probation and a felony charge for a sign! So 1 1/2 yrs ago I stopped going to my P.O.s because he made me take a drug class even tho I never failed a drug test for him the last one I failed was about 1 1/2 yr before that with a dif. P.O. The class was once a week and I was staying 2 hrs away working and could not afford the gashomosexual remarks to me and I don't trust the law or judicial systems anymore bc they screwed my life up so I did not report him I just stopped going. And now with just 1 yr left on my probatiom the quire P.O. Violated my probation for using illegal drugs(it has been 3+yrs since I smoked pot) and failure to attend the drug class which I should have never had to attend in the first place. With all that said I guess my question is, what can I do to get this taken care of without facing jail time? And just because I have a bench warrant out does that mean I will most lilely face jail time or could I get all this dropped with a decent attorney under the circumstances?..
