We laugh when we're sad and cry when we're mad. Some days its all just too much. We're worn down and soul weary. It takes a concentrated effort to stay on top of responsibilities. Duties at work and at home demand a percentage of time and energy.
Relationships require upkeep.
Time becomes a precious commodity and there's never enough of it on any given day. It's far too little. Everyone and everything suffers when you go through the motions of your day in an exhausted stupor. You can't give until you're empty or 'do' until you drop. Self care is not a luxury, it's a priority.
