Hello. I' ve had depression and anxiety attacks for years, adrenaline is NO friend of mine, and had some rather severe health problems for about 3 months now. I'm nauseous, shakey, no energy, headaches, no appitite, stomach pains, diareah, very jumpy, have either hot flashes or cold sweats, a lot of trouble sleeping, I'm always exhausted no matter how much sleep I get, I've lost a lot of weight, I'm irritable, my concentration and focus is shot. So far all blood, urine and xrays have shown is I don't have pneumonia, mono or whatever else they test for at hospital. I have this thought, idea, whatever. Is it possible that my stupid body has locked itself into fight or flight mode?
