I have severe brain fog, extreme low energy, body aches all over, aching knees, and a very difficult time getting going every day. My diet is very clean, lots of vegetables, lots of organic juices, lots of water and some meat. No fast food. My drive is at the lowest point in my entire life. I am 59 and very concerned that I have some disease. Also, I have memory problems and almost no desire or drive to anything. Am I in trouble?
