How to be okay during no contact when you don't have support around you

I moved to a new city and he's the only one I know around here. I have wonderful friends, but they all live far from me and there's only a few that I feel comfortable reaching out for support. There were so many things that I was excited for us to do together, places I wanted to visit, people I could get to know. Right before no contact, I even met his friends. Now, there is no one. It hurts me to know that he has a good support system around while I feel like there is no one around me. It's also difficult knowing that he lives in the same apartment as me, just a couple floors down, and yet we might never be able to see each other again.
