Oh! That's what I forgot! I just read somewhere that people with abandonment issues typically sleep with some sort of noise: a fan, a sound machine, traffic. It's thought that silence triggers their abandonment feelings. I know this really resonates with me. I hate silence. I've told L to never sit in silence with me, that I hate it, and it doesn't help. And I do sleep with all 3 sounds I listed. Especially can't sleep without my sound machine! Even when I drive alone, even if I'm playing music, I crack my window so I can hear traffic.
