The day isn't over yet.Perhaps do something small every hour,or two?Perhaps do some self-care,....shower...eat....put some nice music on....and get back to your goal?Maybe you won't do ALL of what you intended...but...even a bit will bring more peace than none? Messes happen.That isn't a fault.Calling yourself a loser won't help in any way and is self-defeating.There's no point in it.Walk away from it for a short time,grab a beverage...have a bath...and get back to it.Do something small.
