My kids don't need to be homeless

me and my 4 daughters will be homeless, my oldest is handicap with a DNA mutation that will take her life in 5 to 7 years, I lost my job right after hurricane harvey due to me having to take off work to take my daughter to her appointments, for 2 months I've been looking for a job that will work with my kids scheduled with school, I'm a single full time father and the mom isn't in their lives, please help
