When my dad died, I didn't go for a long walk in the woods. I found a secluded spot in the woods and just sat down alone and reminisced. I recalled something I thought I had forgotten. When I was very little, every night, my dad would tuck me into bed, and I would tell him that I had a secret. He would bend over and offer his ear, and I would whisper "I love you."
When I remembered that, I broke down and started crying. I cried like a blubbering little baby for the longest time.
The crying helped. It really did help a lot.
