Horrific personal experiences, thanks for sharing.
Your idea about one-day self-love trial seems great, I'll try it out. I think I'll start with a 30 minutes hot foamy bath, but I don't know how will I cuddle with myself. :/
I've also just expressed my thoughts about depression and self-acceptance in Why should we become a three-legged dog?, there are some advice inside that might be useful for you.
I've followed you, cheers!
