Someone posted this article to me about how kindness improves mental health and I thought it was really wonderful. It starts with a story about Hannah Brencher, who found herself gradually unravelling. She started writing love letters to strangers and leaving them in public places - she left the first one on a train, addressed 'If you find this letter, then it's for you'. She noticed that her loneliness and sadness took a backseat and she could take the focus off herself. She has since started a wonderful campaign to write more love letters. I found this really moving and beautiful - how inspiring!
