Instead of suggesting to take a break, which isn't bad to do, we all been there but change your daily chores. It might sound funny, but instead of let's say doing roulette's/leveling alts/other jobs, try something new. For example, go join some party finders or some raid content, or relax and try some gathering/crafting. It might not sound like fun, and in most cases it isn't but after you've done it for a week lets say, switch back to your old routine. All the sudden you might actually start enjoying it again, and while that's still temporary, at least it won't burn you out as much.

I noticed when taking a 6+ month break, that sure you have lots of content to run when you return, however the pressure is much higher because now you need to play the stupid catch up game, and some content will be "old" to that time, making it either unavailable since people don't want to run it anymore, or expecting you to be very good at it. Meaning you will have to put lots of research into that etc, instead of right now still falling in the grace period and could say, I am new/blind run etc. Taking a break should be your last option in my opinion.
