Need help asap for my family

Hi, im on here asking for help to provide for my family.
i am in the process of getting a divorce and i am trying to find another job so i can keep a roof over my families head. I am the only one working right now and I am behind on everything and I do not want to lose my house, I rent my house and my landlord will only work with me for a short time before he decides to evict us.
I am currently taking care of myself, my two kids and my sister and her little boy plus shes due to have a baby in 3 weeks. and my dad may have to move in soon. 
All of us live in a small 3 bedroom house and its very crowded but we are making it work somehow. 
My husband was cheating and was blowing all his money so i kicked him out and i am filing divorce but with no other income its getting harder to keep up with the bills. ive been selling what i can but its not enough.
please help me
