He left the house!

Im in abusive marriage 8 yr with 2 kids(6 yr and 2 yr). Yesterday i went to domestic violence local office. But didnt got any help from them they said they can find shelter only for 2 months and its not enough time for me to save money with 2 kida. So i was saying on the phone to my sister and he heard everything... When he came he was so mad and promised me he will take kids custody and will show me too. He packed and gave the apartment keys to me and said im gonna see u on the court! So now im with kids with no family and no friends i suppose to be at work today at 4 pm and i called out coz there is no one to watch my kids. Im lost. I dont have money to pay the rent i have no help to watch the kids. I probably will loose my job if i will not show up. Any advice???? What should i do???? Where can i get help???
