I cry. I wait till I get in the shower and then I cry just enough to relax the spring of tension in my gut. Then I go on and continue.
Or, if im in a situation where I cant cry, I pray. I tell the Lord how infuriating this all os and how unfair and how glad I am that I can take care of him and to please keep me strong. It helps me to know He is listening st the very moment I need a listener.
