I feel isolated

Not having a specific place of worship to share similar beliefs with others is really getting to me. I live in NYC so you'd think there would be groups for Hellenic Polytheists like myself who can find community in but nope! It's mainly just Wiccan or Satanist crowd of paganism. I hate celebrating my faith alone, doesn't help that I have a chronic agnostic & absurdist mentality. Help!
