Sometimes...

...the only to keep going is to do - do anything, fill the time, occupy your mind - anything that keeps you from thinking, from remembering, from the sadness.  Time does heal.  The sadness isn't as oppressive, but still, it creeps in on certain days.  Trying not to wallow, trying not to give the sadness room to come in, keep the spaces filled with activity, so the sadness won't.
