First, you need to drink more water, the dark urine
tells me you are not hydrating yourself enough, and
if you want to feel good, you must drink at least 8, 8 ounces of water a day.
Your cholesterol is fine, I would not worry about that number.
As to the other symptoms, it appears to me that you are coming down with a good case of the flu, I would get into bed, drink the water, and start taking extra Vitamin C, Vitamin A and vitamin D.
