I am so sorry this happened to you - and yes something happened - your husband is wrong there - its hard for him to understand -
Im sorry he went away - Im glad you are staying at your mums place and agree that a psychologist or therapist would be able to help you through this and that you do need and deserve help.
Please think about looking into a therapist - PTSD is a very hard thing to get over and a T canreally help you.
Come here and post as often as you need to we are here to support each other and to help with information where we can.
P7 sending safe hugs if its ok

When you have come to the edge of all light that you know and are about to drop off into the darkness of the unknown,
Faith is knowing One of two things will happen: There will be something solid to stand on or you will be taught to fly.
