Anything is fixable with the applicable of money. I don't think you got hurt bad. You'll need to figure out when you want to end up to decide what you need to replace. On most cases, the cost of replacement parts will not be that bad (unless you find out that major parts like the crankset need to go), just sort the problem out before applying money (do not throw money at the problem and expect it to solve itself). You can install the replacement part yourself, and resell the parts that you take off to recover some money.
