Help is needed badly

I am a single parent of 5 kids, my childrens father left me 14 years ago and ever since everything has been rough for us. I was raped by my mother's boyfriend and it left me in a state of mind to where i could not function enough to keep a job it seems the more I try to accomplish a goal I fall into a glass door. I am in big trouble because i live in a small house and I moved in here 3 years ago the rent was 500 dollars a month. Last year the landlord went up on the rent again and I was struggling very hard to make ends meet. Now it is a new year and now the landlord want me and the kids to move because he's ready to sell the house but I don't have funds to move and I have tried everything I can to find me and my kids a place that is affordable. I suffer with anxiety and post tramautic depression it hurts me and i fight so hard but i keep losing. I am afraid me and the kids will be stuck because I don't have no where to go. I need help so we won't go in the streets i need to have the money to move. Being alone is no fun especially when you doing all you know how. I pray God sends help. Thanks everyone.
