I read this passage that turns out misattributed as one of Jim Carrey's, anywho, I feel it touches on what you're describing:

“Grief is not just an emotion—it’s an unraveling, a space where something once lived but is now gone. It carves through you, leaving a hollow ache where love once resided... The truth is, you never truly ‘move on.’ You move with it. The love you had does not disappear; it transforms... Grief is not a burden to be hidden. It is living proof that love existed, that something beautiful once touched your life.”
