please help me.

I am so overwhelmed. I have 7 children I work full time I go to school full time, and I am almost done completing the job training to work from home as secondary job. I have certification in the morning in order to do so. I have not done my college homework this week and could fail. I can not concentrate because my teenager daughter and husband are fighting. I am so tired, my husband cant find work it has been that way for three years. I dont have a car, I pay 1300  every month on rent but I am behind still my 4 stepkids are here, and we barely got dinner done in time. I will work so hard if you can just help my family be peaceful, pleae help me find some way to catch up. I have no family nearby, no family with resources, and just want to succeed. Failure is a large homeless family and no hope. Please help the turmoil, please help the money, please help I beg. Let me know I am not alone.
