MY LIFE IS RUINED!!

Hey guys, I am really depressed right not. I registered for classes at university of Houston at the same time I did to my school at Houston Christiam university. And so when I finanly made my mind on which to attend. I guess I was suppose to drop the classes from the university of houston. But I didm't and now I have 4 F's and $5000 to pay. Guys, is there anything I can do to dispute this? My family is not anywhere near able to pay for the $5k and especially for classes I never even attended. I also want to go to med school and I am a 4.0 student but not my dreams are crashed because of me nnot dropping any classes. Any feedback is accepted.
