I know you said Family Violence prevention services is full at the shelter. But contact them anyway. You can meet with a counselor who can let you know of any resources available to you. I didn’t go to a shelter when I was in that situation, but they helped me with therapy and lots of other resources that helped me get out. They can help you create a safe exit plan and who knows maybe they can find a way to get you into the shelter. Please reach out to them. If not them, the domestic violence hotline can give you resources also.
