I have gone through some of the things that you are going through. I have three children with no support from the father, and also one children that use to take all of my attention. She has since grown out of it and I learned how to spread myself amongst my children. It is still hard. I am a fulltime student working on campus and decided to take a chance and depend on God to take care of me and my children. You have to be a go getter. Take a look at my page and see if there is anything that can help you.
