Things that were hard to bear are sweet to remember.

Difficulty often looks different from the far side of it. Once a hard stretch is over, memory keeps the proof that you got through along with the pain, and the surviving itself can take on a kind of warmth, especially if others were with you. Plenty of hard things never turn sweet, though, and a loss is not obliged to become a fond memory.

If you are in the middle of something heavy now, you do not need to believe it will be pleasant to look back on. It may be enough to know that some of this could later be remembered mainly as proof of what you can carry.
