Also please know, you do not have to give your name or address. You can just talk. You call the national line, and if needed they will give you the local dv shelter line.
I did do this, and I didn't have to wait for any of the phone calls to go thru, they answered immediately. They really are there to help you with whatever you need.
You will feel alot better after that first phone call. Just getting over the fright of making that phone call and to hear that other comforting voice on the other end of the phone.
