One of my individual stocks has CRASHED--what should I do?

a stock I bought a year ago has tumbled 60%. it's not in danger of hitting 0, but 60% is quite a fall. I'm under the impression that it pretty much HAS to go up at this point so I think I should hold onto it, but I'm not sure what my next move should be. For the record, I am only 21 so time is on my side
