Newly diagnosed with Hashimoto's

I was recently diagnosed with Hashimoto's disease, along with vitamin D deficiency. I am starting synthroid tomorrow. I also got prescribed high dose vitamin D and a lasik to get some of the minimum of 15 pounds of fluid I have put on over the past few months. I am on a medically recommended gluten free diet. I have had hives all over my face, but since going GF, the hives are almost completely gone. I lift weights often and can lift 50 pounds over my head, but I am struggling to do 20. No matter how much I sleep, I'm always wiped out and everything on my body hurts. I wake up every night around 1AM because I'm in so much pain, specifically in my hands. My hands consistently go numb. I have lost a lot of hair. I clog the drain every day. When I run my fingers through my hair, it is very obvious that my hair has thinned out.

Looking for some new friends with Hashimoto's or hypothyroidism (or even any other autoimmune disease) for support.
