Unsure of what you mean in your post by logging, if you mean raid logs, or physically logging on (brains burned out right now from class lol).
If it’s raid logs burning you out, due to specs not quite performing the way you want compared to others, try not to worry about it to hard, ive mained demo for a long time, through its good and bad, regardless of its performance compared to other specs.
This let me play a class and spec I enjoy, leading to less burnout, ofcourse I did have a burnout at some point, mid BFA actually, so it happens.
If you mean logging on to keep up with gear and weekly stuff for your Alts, don’t push yourself, prioritize your favorite, and just choose one or two to slowly gear up with it, Alts aren’t meant to be second mains. I’m currently maining an ele sham, but debating on going back to this warlock for demo, so I can alternate between the two during M prog since demo is superior in cleave, where ele is a bit clunky, and honestly feels lackluster in aoe. So I feel your pain, and my best advice is just take your time, play what you enjoy as I have, and you will have a better experience.
If this doesn’t help, then perhaps taking a break from the game is just what you need after all, when I took a break for the last half of BFA I got back into my Dark souls 1/3 SL 1 runs, spent time on Hollow knight, played some 7 days, and it was very refreshing, and I felt ready to go for SL.
