i just adopted a two year old dog and he’s very anxious and I’m not sure what to do

I adopted a male Alaskan husky today. he’s beautiful and I really love him but he’s so anxious and it’s making me think he doesn’t like me or he’s never gonna change. At the shelter they said he should break out of his shell soon but I’m just very afraid. I really thought having a dog would motivate me and would really bring love I needed into my apartment but I’m truly terrified now that he’s home and I will literally take any advice or any words of encouragement.
