Returning to college after a hiatus...need help and advice.

I have just applied for reentry into a college I "attended" a few years ago. Here's a timeline for you guys:

2007: Graduated high school, enrolled in classes at college A. Went to classes for about a month, and had some derailment and quit going. Withdrew before I failed. Still had to pay for the semester, so that's student loan #1.

Spring 2008: Hiatus.

Fall 2008 - Summer 2009: Attended college B. Awesome grades. No student loan.

Fall 2009: Applied at college C. Took out student loan #2. Hated the school and had another derailment. Withdrew from classes before I failed.

2010: Hiatus.

What I need advice on is how to get back into school. Will they accept me even after I've withdrawn and been to so many different schools? Can I apply for another student loan even if another one is being paid for? Is it a smart idea to go back with no idea of what I want to be my major? Any generally motivational stories?
