Help with rent

Hello I'm making this as in hopes to get some help with paying my rent. I'm a mother of 3 and just going through a hard time at the moment. I'm not on income assistance and due to me and my children's father splitting he was our main income besides childtax so things have been a little bit of a struggle. I'm short $380 on my rent for January and my landlord is giving me a hard time about waiting until the 20th. I've called churches and their funds are low due to it being after Christmas. So if anyone is able to help with anything it would be greatly appreciated. Thank you & God bless
