I've found that the best remedy is to just give yourself permission to feel that moment.  The stress and the struggle come in when you try and convince yourself that you’re in a bad place and you need to move on.
The truth is, though you shouldn't park and turn the car off,
you can take the scenic route
no parking1
to your feelings!
