One the many difficulties in grief is that all the usual day-to-day challenges of life don’t cease just because you’ve experienced significant loss.  Computers still crash, interpersonal challenges continue to arise, injuries still occur, children still disobey, work stresses continue, and so on and so forth.

The difference is that you have little to no reserves to cope with these nuisances and struggles.  The slightest thing can push you over the edge leaving you completely disabled and discouraged.
I have found that there are things in my life where previously, before Jud got ill and died,  I could easily roll with the punches, but now I have no capacity to deal with them appropriately.

Every molehill feels like a huge mountain.
