I'm sorry to hear what happened to you and how bad you are feeling. I'm been where you are now.
I had been in a relationship that became abusive. We were together for 8 years and the last 4 were abusive. It was very abusive verbally & emotionally but had exculated to physical abuse before I finally got out & stayed out. If I had not gone for counselling I am sure I would have gone back. For me, the fear of the unknown was almost worse than knowing what he would & could do to me.
You should be proud of your courage!! It takes a strength to do what you have already done. Please continue with counselling & the support group sounds like a fantastic idea. I'm sure you can always find a listening ear from someone here as well if & when you need it.
Take one day at a time and remember you are important and worthwhile. You are not alone.
