THYROID ISSUE

I went to the doctor in March because my eczema came back and was insane. Covering my arms, head, face, eyelids, etc. My levels came back normal so my doctor said I could try from going to 37.5mcg to 50. Well two months later and my hair is thinning. By the time I’m done brushing I have a huge clump of hair. I got blood taken again and will have the results tomorrow. But my anxiety is soooooo high. Someone tell me it’s semi normal if you’re taking too my synthroid. Try not to scare the shit out of me because I’m already a mess over this.
