oh love - i a sorry! sending you comfort and peaceful vibes. I know how hard it is to finally have to face the thoughts / feelings and emotions that we buried with our addiction.
Do you have someone in real life to talk to - a therapist, a friend, a counsellor? I would right down my thoughts - having them on paper made it easier to see them and deal with them and some lost their power over me when they were visual (if that makes sense).
For me meditation helped me find a calm space and quiet the mind. Maybe the meditation thread will be helpful for you-Meditation and Serenity
Make sure to be gentle with yourself. Your body and mind are going through a lot right now. It is ok to feel all the feelings, to sleep / rest as your body needs it.
