I need college money!!?

My parents are out of my life. I am going to be a freshman this coming school year. I already have a full time job as well as a stafford loan and a pell grant. If I place 100% of my earnings from my job towards my tuition, I will STILL need about Three Thousand dollars for my first year.

Do you know how I can make this or at LEAST a majority of this money? I have NO idea what is going on, and it seems WHOEVER I ask either doesn't want to help me or does not have the time or knowledge. If you know of a sensible way I can get through this, PLEASE HELP ME!!

How did you pay for college?

Did your parents help you? Did you do it on your own? Did you get a lot of scholarships, grants or loans? I am so lost.. .and it feels like it's too late to apply for grants or scholarships. I think I'll have to rely mostly on loans.. I don't have a very high GPA so I didn't get a grant or anything :[. But I'm going to a community college, and I think I'll be ok.. I don't think it will be more than a thousand bucks for one semester, am I wrong?
