Maybe consider camping in a village? I went solo last year (my first year!) knowing absolutely no one. I camped with the village of Hushville and had a wonderful time. For me it was just nice to have a set place to go once I got through the gate, helped ease my anxiety a bit, but like others have said you will make friends with your neighbors wherever you camp so don't worry too much about needing to be with a camp, it really isn't necessary.
And congratulations on finally making the trip!!!
