Thanks for posting.
Playing poker as a job is equivalent to being an Air Traffic Controller in number of decisions per work hour. Plus the intensity of those decisions.
They have done numerous studies on ATC to figure out how not to get to Burn Out.
Most commonly ATC are given multiple days off in a row to allow for the proper rest.
One group works 6 days with four days off.
As an estimate: if you have been grinding 6 days per week for 4 weeks you should have had 16 days off and you have had 4.
We can break ourselves emotionally and mentally. The ATC schedule is to alleviate that.
You seem to have pushed yourself into the burn out zone. Rest away from the game is the only thing you can do.
Add in trying very hard to make your rest very pleasurable. Spend time doing the other things you love to do.
Hope this helps.
