Grief is the last gift of love.
It hurts so much because you loved so much.
That's the strange mercy of grief: it's proof of the bond. We don't grieve what didn't matter. The depth of the ache is a measure of how deeply someone lived in our heart.
It doesn't make it easier. But maybe it makes it a little more bearable to see the pain as love, still speaking.
Let the grief be what it is: love's last gift, and a sign that something beautiful was there.
