Melonpony,
I'm on anti-anxiety medication that has been working well for me for several years, as well as actively seeing a wonderful therapist and regularly getting acupuncture (which I've found is hugely helpful with my anxiety.) My anxiety levels are actually at an all time low for me, that's why I worry it may be something else.
The doctor had the nurses run a blood test on my thyroid (which is what she has done continuously for the last three years when I express concern to her about this problem) but it came back normal and she didn't run anything else, even when I asked her to. She also won't write me a recommendation to see a doctor who specializes in Gastroenterology, which my psychiatrist and therapist both recommended I look into.
Her refusal to help me look into this is causing me the most anxiety I've felt in a while, I think you're probably right and I should look for a new doctor
