Help! Does this sound like tyroid... I have been feeling overly exhausted recently wake up and feel like i could go back to sleep again! I also keep getting a fuzzy brain and just dont feel myself i have always been cold and my nails and very brittle and keep flaking and as for my hair the ends of them are awful. My periods have always been pretty heavy. I just want to feel normal have been feeling like this for weeks now! Also have the urge to eat so much food recently ! I have a blood test on wed! But just wondered if this sounds alot like tyroid probelms ! Hope someone could help!
