mentally...please call the hotline. It costs you nothing. You have everything to gain from just *talking* to someone there.
I called the hotline in my area while I was at work. I locked myself in a conference room and just talked with one of the counsellors there. She listened to me, took notes, told me I was right to have called them, and referred me to three local shelters. She also gave me the names of lawyers in my area who could help me get a temporary order of protection so I could get custody of my daughter. She suggested things to do if the situation got out of hand...It was really great just to talk to someone who didn't think that "It's not that bad" because I hadn't been beaten to a pulp.
Please keep us updated. We're worried for you!
