I am so tired of feeling worn out all the time. I had my thyroid tested and it was fine. I cannot go anywhere without having to sit down at a bench because I am so tired. For example we took my son to the zoo last week and I was so tired I sat down many times. I am only 23 5'4 180 pounds. I am going to see my ob/gyn next week...can she help me out at all? thanks
