Hypothyroidism

I'm just curious if anyone here also has it? I was recently diagnosed. I'm only 20 and would love to hear any advice anyone has? It caused weight gain that was previously never a problem for me. I was always very skinny, actually. I feel like I'm not in the right body. Did you loose weight more easily with treatment? Did you get back regular cycles? Is your sleep pattern normal again? I just wish I had more.control over my body.
