I absolutely feel you on that regard.
I realized one of the biggest issues is that I would beat around the bush and only ever really RP with friends and random strangers once a blood moon and that really only cemented at how lonely I would get in game. Eventually I’d burn myself out on PvE/PvP and then I’d just feel like quitting/not playing despite being subbed for months at a time.
The longest time I’ve not played the game was the entirety of WoD because I just thought it was at that level of stupid that it wasn’t worth playing.
My advice? If you can do it, apply for an RP guild that you think might work with your character. Forcing myself to go and find a guild and joining it has made me suddenly far more attached to this vulpera here than I have been in a long time with my old main, Wolf. I suddenly had a guild that did a lot of RP events, and while it isn’t required to go to every single one, I try to attend (though some of the events are a bit too big for my anxiety and headaches to handle) and I end up enjoying myself.
Slowly, but surely, I have been making friends in WoW again. I was playing solo when I came back a few months ago, but now I have a few new folks who wave at me while the very few “old guard” friends occasionally complain about WoW to me in bnet and both sides give me a feeling that maybe I can keep playing for a little while longer.
So yea, my advice is to just find an RP guild you think might be fun and take a leap. Who knows, worse case scenario is that it doesn’t work and you quit anyways. But it might be just the thing you need.
(Also, I recommend Firebrand Enterprise they’re genuinely very active if you’re into Horde RP and have been swell to me.)
