Single Mom with 4 kids fund

I'm a Single Mother,  in the final stages of getting a divorce in the Bay Area of CA. I have 4 children, Boy 6, Girl, 5, Girl, 4 and Girl 22 months old. I have currently lost my job as a Recruiter working for a major company, they ended my contract early. I am actively searching for a job where I can afford to support my 4 children. Unfortunately, the father of my children does not take any responsibility for his children whatsoever. Seems like he finds all the loop holes in the court system  to get out of paying for anything for his children. There is no current court order for child support or child expenses, therefore he refuses to pay anything to help out his own children.  I'm at the mercy of the CA court system where my case
keeps getting delayed. Raising 4 children on my own has been quite a struggle and now losing my job I'm severely stressed out. I've never been in this position to have to reach out for help, but I am truly in need and would appreciate any help that could be given.
