I am 66 years old, female. For approx. I have been feeling tired with fatigue, weakness, dizzy when I stand up, my tongue is swollen and I have a monster of a headache. Most of the day. My eyes are sore to touch. I looked up signs of dehydration and that seems to Be accurate. Before I felt so weak and fatigued and all the other symptoms. Last year I was diagnosed with depression, anxiety and sleep disorder. I also thought I might have Adrenal Fatigue. Can you tell me what it is? Thank you.
