OK so here it is: I have a lot of random symptoms that seem pretty common and lead to very common issues, but the thing is everyone says im fine and their is nothing wrong with me.I have had exstensive blood work and have even seen specialists. Maybe im just crazy, but i feel like my symptoms are not normal. I believed it was hypo thyroidisum(i think this is the slow one) or anima but it is neither. here are some detailed symptoms Dry brittle weak hair( all my life it has never ever grown, i cu it and it doesn't get any longer) Tired randomly even with good sleep cold frequently/ sensitive to cold irregular periods This symptom is the most excessive Impossible weight loss/ gain weight easily ravenous appetite: my appetite is so extreme that it gets in the way of everyday life Even though my appetite is extreme and losing weight is hard i have managed to keep a generally healthy weight: I am 5'7 and 130 pounds I eat fairly healthy and workout frequently
