Just Diagnosed with Hashimotos

Hi everyone. I was just diagnosed with Hashi's two days ago and I am feeling a bit overwhelmed. I am a 24 year old male so I feel like a bit of an outlier to be diagnosed. I had never heard of Hashi's before being diagnosed so I am in information overload right now. Any helpful advice on where I should start, things I should research, and the best first steps I should take would be greatly appreciated!
