Sometimes if I'm by myself and I can't sleep, I just say (in my head) "I love you, _____" to whoever comes to mind.
Once I've gone through all of the obvious loves of my life who I see regularly, people I almost entirely forgot about will come to mind which is sweet, and sometimes people I don't like will come to mind, but because I'm so sleepy I'm like ok whatever all is forgiven love you, which is freeing.
Anyway it feels like I'm sending little wishes to everyone :)
