Mary Wollstonecraft Shelley said this quote

If grief kills us not, we kill it. Not that I cease to grieve; for each hour, revealing to me how excelling and matchless the being was, who once was mine, but renews the pang with which I deplore my alien state upon earth. But such is God's will; I am doomed to a divided existence, and I submit. Meanwhile I am human; and human affections are the native, luxuriant growth of a heart, whose weakness it is, too eagerly, and too fondly, to seek objects on whom to expend its yearning.
