When you open your terrible schedule at the end of a session, you need to clearly understand that poker, like our whole life, consists of black and white stripes. It can't be always bad, as always good. After an unsuccessful day, a new one will come, which will definitely bring much more profit and good mood.
With a series of bad days in mind, you shouldn't think that your game is a complete mess and that you are not playing poker well. It is possible that in the wake of bad days, your game may deteriorate, and your attention will be distracted. Take a short break and do something other than poker. Personally, I prefer to get together with a group of friends for a webinar and relax with some online games.
