CPS was called by my family and I took a mouth swab test. My caseworker said I failed for methamphetamine which isn't possible. I took a UA at a facility and passed. She still placed my son with my cousin, and refuses to let me take my tests at a facility. She has called me a meth addict where anyone could hear. She's constantly rude, unprofessional, and insults me. What can I do?
