ok so they asked you to do a drug test and you refused and left the program and then after leaving the program you called your case manager.

and now you are upset because everyone is worried about you and discussing you behind your back....

these people who are talking about you to each other are the treatment providers in the program you quit because you didnt want to take a drug test.

most IOP's have a termination process that includes the client signing papers saying they are leaving the program and that they are no longer responsible for that persons care. if you walked out with out doing the termination process then they are still legally considered your treatment providers and can legally continue to discuss you with each other.

my suggestion contact your treatment providers with the IOP and let them know you want to close your file/terminate with them officially. they will schedule an appointment where you can sit down, sign any papers needed to stop the program and the papers needed to stop then from talking about you with your present treatment provider\case manager. your case manager can also tell you how to officially terminate with the IOP if thats what you want to do.

how to get them off your back about the drugs issue... thats simple do the drug test. if you are not doing drugs then you have nothing to lose but everything to gain. the test saying you are not doing drugs will be all the proof they need.
