I am so sorry for what you are going through, emotional abuse is so very painful. You do deserve better and in sobriety you will find the confidence to seek that. I also would recommend rehab. One, it will help you get sober. Two, it will give you some space away from your abusive husband to really think things through, soberly and with the helped of a psychologist. You are WORTH taking such a big step to care for yourself. If you have any questions about rehab you can search for my old thread, I made one about my rehab experience, it was wonderful and just what I needed to get sober.
Sending you a big hug!
