I'm disabled never charged of selling drugs b4. But over3years ago,an undrcover coerced me2get them drugs.Now,I know was illegal.Do I have case now?

I got put on probation for 10 years and huge fines. I did one year, then got a reckless driving for not stopping at a stopsign and they started my probation over, so I've been on probation 3 years and have 9 left. I've have electric shock therapy 8 times. They took advantage of me. Can I get off probation now and get this cast dropped now that I found out what they did was illegal? My lawyer didn't tell me that then
