I am so sorry to hear of you fears and I know they are valid so please keep talking to us and we will do the best we can for you.
You state you were looking for a site that dealt in Domestic violience............Here is one I like.
Stick with us but take a look at this forum too as it is dedicated to your problems. God bless.
We are here to listen and support at HW. You have been given some great resources by our other members so I won't clog up the screen! Please take the steps you need to stay safe. If your ex makes one single wrong move, you need to contact the authorities. We can provide a safe place for you to talk and we can give tools on how to deal with anxiety, but we cannot help when he turns up on your doorstep with menace on his mind. Take it from a domestic violence survivor. This is serious stuff. Your safety is number one at all times. If you feel scared, or need help with finding the right head space to get help please email me okay? I have been through this and it messes with you if you don't take action.
I wish you safety and peace of mind.
