How do you deal with mental tireness?

Hi. I do see myself being tired mentally even at work almost every day. Even people would tell me I look tired and that I seem to be out of this world. I feel tired mentally and can't do much. Heck sometimes it's hard to talk. For me it's hard to even feel emotions.

Anyone managed to get rid of tireness? I create content and I would love to have energy to make it. How would I make good quality content if I'm feeling tired a lot?
