If you are subjected to psychological violence over a period of 2-3 years, you can get adrenal failure from it?

Unlikely, however:: "Adrenal failure" is a strong term and, fortunately it is very rare. However, ongoing stress often leads to suboptimal adrenal function or adrenal fatigue, which is very common (though this is controversial as many Drs. don't recognize it). Reducing stress is an essential part of recovery. See https://dailyhealthpost.com/adrenal-insufficiency/ and consult with an integrative doctor.
