How do i get my mother to understand me more?

I am a mother of seven, with no regrets about my children at all. I got married about 4 years ago to a man that I knew had problems(the father of my last three children). I had already had my fill of his disappearing acts that he pulled to use crack cocaine, which I never allowed around me , or my children.Every time I tried to leave him , he would file false reports on me ,and a social worker would show up at my door.I have three other siblings that ae not affraid to show their weaknesses, but I am.I don't know why,but I can't ask for help of any kind usually.But when I do ask for help it is because I desperatly need it,in order to keep my children. when I ask my mother for help of any kind, she reams me out and tells me that I'm a big dissapointment to her, but she doesn't do that to my siblings.If she would take me seriously, I would be able to kick my husband to the curb, and pick myself back up.I already have a small business started, but with all the kids , and tons of laundry, and cleaning,etc.It seems like Im not getting any slep at all, with him gone. all I asked her for was ...would she please watch the kids so I could nap, and she told me that the kids would be better off with her, and a bunch of other mean stuff. In my mind I am doing my very best to balance a small business and being a single parent of alot of kids.they deserve the very best, and Ill be damned if I going to let them down. Its bad enough that their father keeps abandoning them.they are little troopers, and I need my moms help a little to weed the trash out of their lives.what should i do or say, to make her see that even i need a little help now and then. one of her solutions was for me to get rid of the business.And then what, go on public istance. what is that showing my kids?
