Make sure you're at least getting proper sleep and eating something. Even normal people can get hypoglycemic so an apple or a box of orange juice and perk you right up. 
Coffee and other caffeinated things don't just mess you up if you drink a lot of it at once, but a long period of just a cup a day can make you feel pretty bad. Try and do just a week without it. Make it easier by getting some of those Mio water drop things so the water doesn't taste like lead.
Consider how much alcohol you've been consuming in the last bit and also remember if you cum a lot in a short period of time you can run your srotonin and oxytocin dry. If you're worried about that try and find someone you like and hug them. Even in VR. Failing that, get a weighted blanket.
If you're feeling burnt out, it can be tough to even try something new but you'll feel a lot better if you get a game in your backlog started.

Always remember you can do it.
