I THINK MY RIGHTS ARE BEING VIOLATED What Do You Think?

im a person living w/cancer. My meds makes me sick and nausea so i was self medicating myself with marijuana. then i got into a lil trouble with the law,had to drop urine but of corse it was dirty.The judge looked at my fileand yelled my head off about something she didn’t know. “There is no such thing as medical marijuana in the state of Ohio” she said. she ordered me to probation and drug rehab. Iwent to glenbeigh because i didn’t want to go to jail for PV. i talked to somebody there and they sent the info to my probation off.Saying i could stay as long as my dr.didnt put me on meds that contain THC.remind you i didnt get this letter. I go to the dr.during all of this,and told my dr.the problems i was having with the meds.He prescribes Marinol (THC) pills.NOw im taking my meds wiyhout the sickness and everything is going smoothly. Know my probation off. is on my back because Glenbeigh sent her this letter, and she wants me to see if my dr. will change my meds. do i need a lawyer?
the probation officer knows that she’ll be crossing the line,thats why she wants me to take this letter from glenbeigh that was addressed to her and let my doctor see it a try to get me on something else.which im not going to do because i think i have the right to stay on the meds my dr. prescribed. And if i tell her im not going to do that. Would that be considered as violating my pobation?
