I always feel tired when wake up in the morning, my eyes feel like a lead?

i am 29 years old and female. i always feel tired when wake up in the morning, my eyes feel like a lead. Sometimes feels so tired that i don’t realize the whole day has passed. Big appetite, always hungry. Sleep 6 hours a day or more but still tired. my brain feel like in haze. Sweat a lot. My hands are dry but my face and whole body is wet because of sweat. i tested for hyperthyroid before, took medication and my tsh level went back normal. But my symptoms didn’t go away. The doctor tested my blood three more times but the result was normal. i cannot tolerate heat. my hands always feel like they’re burning up. i just want to know is it normal to feel this tired
