Well not everything is candida by itself and is more complex of inter-related health problems. The anxiety is likely related to brain health, the nasal problems have their own cause and the acid reflex have their own cause very likely. So if you address each one the proper way, all at the same time, it should get better pretty quickly hopefully. The only problem is you aren’t going to the right doctors…the doctors you are seeing just prescribe medication and and don’t look at the root cause of the problems. A holistic/naturopath doctor will prescribe nutritional supplements, homeopathics, digestive support supplements, etc. and will determine what is the best treatment plan for you to get better. So you are going to the wrong type of medicine/profession imo.
I’d also look into the candia5 test for diagnosis if you are interested.
