What do you do about life

I’ve been with my baby daddy since I was 14 years old. We had our first child when I was 16 even though we had our ups and downs I loved him and put myself and the kids through so much to keep our family together. After we had our third son the next two came like wildfire obviously we were meant to have a family right ? He had never just abandoned us before he always left to cool off or whatever but this time he left state leaving me alone at 25 with 5 boys under the age of 9 two of them babies two of them ADHD with no money, no daycare, and no ride. These last 3 weeks with me working and taking care of all five boys with no support system no friends and only one family member to help when they can has made it impossible to go to work. Their dad doesn’t understand that if he doesn’t love me that’s fine but I need you to help me with these boys I can’t possibly raise all five by myself as a CNA not being able to finish school to be a LVN no making it to work so no extra money no money at all. My mom let’s him talk to the boys behind my back and then tells me it’s my fault I’m losing them. He left as soon as we opened a CPS case for our son having been abused at school what can I do he knows we’re struggling and he refuses to come back and even help or try to work here or move us/ or them there. What can I do ? I can’t lose them against my will to CPS that will take longer for me to ever get them back . Even though he never held a job I always made sure we had food or a ride or a roof over our heads I’ve given my life to someone who seems to not be greatful for his kids. I know he loves them I wish I could understand why he would leave state and leave them behind. If I’m as horrible as he says I am then why leave them with me knowing I have no family or friends to help me with them only sending me a 100 or 200 a month when your threatening me telling me your making so much money. What do you do when life happens?? I have no job to support all five hardly any child support at all no one to watch them so I can even pee and yet I’m wrong for feeling as if I’ve failed them after working so hard all these years through all the pregnancies.
