Talk to Endocrinologist on Symptoms Of Tumor In Adrenal Gland (Pheochromocytoma)

I have severe anxiety, palpitations, high bp, constipation and random flushes/episodes of delusions/hallucinations kind of thing, I don't know how to describe it, but it's like I detach from myself. I have already gone to hospital in emergency once when my bp suddenly shot up to 170 and I had tightness in my chest. The doctor thought it may be a case of pheochromocytoma but later on just said I have anxiety issues. I have tried all kinds of medications including SRRIs, benzodiazepines but the nothing is working. Can you help me in consulting this, perhaps a physical visit?
