Need advice on what to do about payment

Hi there, it’s a fairly long story but due to reasons that we’re basically out of my control (with other stupid decisions on my part as well) I was in academic probation last semester, and I had to enroll in an emergency loan through my school in order to continue in the semester bc fasfa wouldn’t cover it, I’m out of it now, but I’m also trying to take summer classes, but it won’t let me until o pay the 5100 I owe. I was thinking about using one of the private student loan sites to pay off last semester, and my summer classes, with the hopes fasfa covers next semester, but is that even possible? And if so does anyone know the best option to take, or if there’s another way to help me out of this situation, thanks in advance.
