Bike does not look so good. Most of the parts are generic, in particular the hubs and bottom maker is not listed. You should look in your area if a bicycle maintenance course is being given, the knowledge is worth the money. Try craigslist, or even ebay. Garage sales. Cruise the recycling pick up routes. I really think that bike might be a maintenance headache if you ride it regularly.
Even if all you can find in the trash is a frame, you can build a decent single speed up from there. A young'n like you doesn't need all those gears anyways.
