When I was working on a rp server. I was so, so, so deep into the story, I was a admin because I had helped so often with the other admins and played in the story. But... The owner of the server was... troublesome? They focused more on the NSFW side of the server, they didn't balance some of the stuff, and oh yeah they made a side part more important than the actual matter that was MENT to be the focus. As it got worse and worse, me and a friend started talking to the owner, they just said, "yeah I'll work on that" and guess what? they didn't, they hated how I played, because I made a npc who was MENT TO BE TOUGH, and they thought it would be to hard, WHEN THE POINT WAS A WAR!
(Edit): the friend who helped me talk to the owner, and was trying to fix it as well, left not long after that happened. I was on my own trying to fix things.
Okay... so sorry for starting to rant but, this shit was so annoying, so painful to watch as I was invested, and soon I felt like I couldn't do anything, I slowly looked at the sunken cost fallacy. I had to leave, I was getting to pissed over a game, and was watching as the fun game become a burning pile of madness and unwarranted rage against me and them. I left, it hurt so much as I was pretty close to a friend in there... we did a sad leaving rp... I cried from the pent up emotions, the sadness of leaving, and just the want to FIX IT, but knowing I would only get more and more enrage, tired, and burnout.
(Second edit): how I got over the fact that most of my cooler friends hanged there, enjoyed things even if it was busted, and complained but stayed. I simply looked for a new group of friends, and enjoy life after feeling that void. you never forget it, I think, but you try to look past it.
