Hypothyroidism and feeling ill

Hello and welcome, why is it I'm on treatment but still feel unwell? How many people out there are suffering like me but are told "well your on treatment so i cant see why your feeling the way you do, it must be depression" I feel we still live in the dark ages when it comes to health, i don't need the doctor suggesting that its all in my mind, its enough to make you go crazy, all because they don't really know there selves. The amount of people that must have been locked away in the past because of this condition truly breaks my heart. I feel like the doctor would like to lock me up if he could, all ways putting my symptoms down to nervousness, I'm at my wits end, what do you do in a situation like this? Theres more to my Hypothyroidism i know it, and every instinct in my body tells me, this constant feeling of tiredness are not normal, the brain fog, forgetfulness, feeling cold all the time, and so on, if i feel down its because of this!!
