Been there. Try this book:"Self-Compassion" by Kirstin Neff,
she has website too. Put all your energy into being kind and
caring to yourself. You are SEPARATE from this person and what they did,and though painful,it is YOU who is giving you
pain NOW; and it is only you who can alleviate it . . .when you
think you've suffered enough and decide to pack it in and LIVE!
COURAGE+Compassion,
