Has anyone been diagnosed with pseudopheochromocytoma

Hi. I had man symptoms of pheochromocytoma (tumor on adrenal gland) including very high blood pressure, high heart rate, sweating, flushing, terrible anxiety (unprovoked) and others. Your body essentially goes in to fight or flight mode for no reason. I was given clonidine for these rare occasions. Otherwise BP was normal. The episodes became more severe and frequent and I had the testing done for this which came back negative. Apparently out of 300 people tested only 1 will actually have tumor. So the rest of us are referred to as Pseudo pheo. Just trying to reach out to others for support. Thanks for any feedback.
