I now believe that you need to do your closure as you go along.

I don't believe you can get good closure after a bad relationship, or if you are feeling disconnected, or under time pressure.

I've beaten myself up over my poor performance when my mother was dying. But I now see that with the best will in the world, three days simply wouldn't have been enough. It is the wasted years, not the wasted week that weigh on me now.
