Need home assistance!

My story is crazy but I have a 2 year old and as of right now I will be homeless soon! I don’t have a job and I’m looking! Trust me I am! I have never asked for government assistance. Is there any place I can go to and get help with rent? I pay $1200 a month and I am 3 months behind now. Please any help would be great! I’m located in Chicago! Please help!!!
