Teen Gothic

So I wanna go to this event on Long Island but I have no one to go with so I’ll likely be going alone. I’m autistic and a loner so Ive struggle to have go to friendships over the last couple of years as well as currently being single atm. There’s a huge goth scene in nyc but it’s pretty rare that they have these events on Long Island where the venue is literally 15 mins from your house so I wanna take advantage of it. How do you navigate a situation like this?
