Need help paying for tuition?

Like many others I am in a financial crunch in order to pay college tuition. I have spent the last year getting a total of 60 credit hours so I could attend a University, in that time I realized that I am not good at math or science and that I should not be a doctor, but my GPA has suffered. This being said there is little funding available. I am in a single parent home that has been hit hard, suffering foreclosure and other economic hardships. I found out that I have a passion for criminology and would really like a chance to pursue this. I have filled out the fasfa form.I also work about 35 hours a week. Does anyone have suggestions? Thank you:)
