Hi! I feel very tired and sleepy throughout the day. Also my hands and feet are always cold. At night while asleep I feel cold despite wearing a sweater and sleeping. Had thyroid, cbc, kft, lft, serum cholesterol, urine, vitamin d, lipid profile, serum creatinine tests. The reports are all normal. Except vitamin d is 21 and serum ldl cholesterol is 74 which is a little low. I have had this issue for the past 2 years. Have suffered with anxiety and depression in the past. Also I lost a lot of weight in the past 2 years.
