/hugs to you. As you’ve discovered the hard way, these forums are a cancer all their own.
Most of the people here have literally nothing else in their lives to look forward to, so they react viscerally to anyone who dares criticize it. That, and the painfully obvious internet standard of psychopaths trolling.
I, too, have abandoned WoW, for different reasons. Actually, I’m still surprised that I can post here, as my account has been over for nearly a month now.
I agree with how painful it is to leave. Leaving after creating an emotional bond with your characters and the story is hard to do. I contemplated deleting my characters and “killing” them off, but it felt too much like killing a real person. Especially this character, my alter-ego. We’ve been sharing Azeroth for almost 15 years. In the end, I took them all “home” and told them they are now free to write their own stories. Yeah… I still bawled for an hour after “abandoning” Eru. Only people with actual emotions will ever understand that…
You’re a survivor now 
Go forth and conquer the real world now! Or at least find something fun to do that doesn’t cause endless aggravation. Life is way too short to put up with frustration, bullies and stupidity.
Good luck to you, in whatever you choose to do with the rest of the time you have in this life!
also: /more hugs There are not nearly enough of those in the world.
