There’s a lot of good advice to improve things by changing your behaviour. It is also worth checking your health. I have had similar issues but it got better after I was treated for vitamin B9 deficiency. I was just plain exhausted but after a blood test confirming the issue and a few weeks of supplements prescribed by my doc, things got so much better. Depression and burn out have also been mentioned and it is definitely worth asking for a depression test if you see a doctor. That shit is so exhausting. When I was depressed, I could sleep like 10h a night and I still had zero energy.
