how to heal burnout

Go to psycologist. If you're actually fried he'll help you. If you're just tired you'll lose a pile of money for 'get decent rest' advice.

📌

Take a break, get a hobby that's totally unrelated to dev (gardening, maybe?), get a pet (dogs ftw), read books, etc.

Basically, you need change.

Burn in

@RememberMe haha, I just got a dog and started working in the garden

Bepanthen.

Puff-Puff

Actually use your vacation/pto

You don't need to heal, you need to takedown

@frickerg holy crap I freaking loved that game. Takedowns were so damn satisfying.

Have kids. You'll go to work with a smile :)

Being honest, I'd suggest you to go see a therapist and/or shrink. That's the best way for handling the burnout.
You could get a hobby, change your work, modify working hours, but all those methods won't work if your really burned out. Having pills and a therapy (long term, not few meetings!) helps a lot.

Been there, done that.

Reduce your load. Get plenty of rest.
