Been fuking tired at work lately.
I've had more energy after wagie labor jobs than now in front of comptuers and going in and out of meetings. By 3 PM I feel like taking a nap that never happened in my life. After work I don;t wanna go anywhere or do anything but maybe Misc. Some days even too tired to fap and give up half way srs.
Is this burnout or something else?

I'm pretty much there right now. It's obvious when it happens.

When the stress levels get so high that you just stop giving a fuk. Earlier this week, I reached a point where I just stopped answering my phone and eventually let other people deal with the problems I had been dealing with. Basically you are just overwhelmed and no longer give a single fuk. It actually worked out, because in that time I've managed to recharge enough where I'm not fully burned out anymore(only like 75%).
