Struggling to Be Heard by My Doctor: Need Advice

TW: medical gaslighting, infantilization How do I get my doctor to listen to me?? She keeps telling me that depression and anxiety are causing all of my symptoms despite my multiple diagnoses from another doctor (I moved states). I asked for a blood and urine test to rule out a disease that my last doctor was considering for me, and she won't even consider ordering the test. She told me it was a waste of everyone's time and that if I was really convinced that she'd make a referral to a specialist. So a blood test to rule something out is more of a waste of time than waiting months to see a different, very expensive doctor to order that same blood test that may or may not give answers?? I pointed this out respectfully and she tried to explain how a referral works and that she usually doesn't order those tests. She's fully able to but won't. We went in circles of me begging to be treated and her talking to me like I'm 5 until I cried. She then proceeded to try and prescribe me antidepressants without informed consent by telling me they were pain meds. (Cymbalta is a nerve pain med too so she didn't lie, but SSRIs don't work for me and I told her this). How can I ask her again over email to order the tests in a way that might get her to actually listen?
