Struggling with Low Cortisol and Blood Pressure

Been struggling with low cortisol, low blood pressure and now some sort of autoimmune anaphylaxis. Where I don’t always have them. But if histamines build up in my system any number of things could set one off. My low blood pressure seems to be the most difficult thing to daily battle. I drink tons of salt which help and take adrenal supplements. Anybody else do anything that has been helpful for them?
