Getting through burnout

I’ve been really struggling recently and have come to the conclusion that I’m suffering from burnout. My anxiety and depression have peaked, I’m exhausted and irritable, and I’m struggling to do anything. 

Over the past week or so, I’ve found that doing anything - even things that usually allow me to recharge such as watching TV, reading, drawing, writing, etc - is tiring. I’ve been getting headaches all the time, I’m shaky and weak, and my appetite is all over the place. I’ve also been struggling more with sensory stuff such as the texture of clothes, noise, etc etc. Everything’s heightened.

How does everyone else cope with burnout? Even just little steps. I know that people say to reduce demands and increase support but what does that mean for my everyday life? Should I just make time to do nothing but lie in bed and maybe nap? Is there anything I can try to not feel so exhausted and hopeless all the time?
