In desperate need

I really don't want to be here but here I am.
I lost my job two weeks before Christmas I am currently living in emergency accomodation sharing a room with a heroin addict and I am down to my last five euro. I have two children that I can only see for a few hours a week because I can't bring them here to stay with me and I gave all the money I could to help pay for their Christmas presents so they wouldn't be disappointed. 
I want to get out of this situation but to rent somewhere private I need a deposit and a months rent which will come in at around 3000 euros. 
I have literally nothing one change of clothes that I can wash every week I can't afford food and I am freezing but none of that will matter if I can have my girls with me on weekends if I can get a new address I can get a new job and everything else will come eventually. Any help would be much appreciated
