You may be able to chase the threads with a tap and save the threads. Check with a local LBS.

Welcome to BikeForums.

Sorry to hear of your troubles. I think the best thing to do is take the bike to your LBS and see it the bottom bracket can be salvaged.

Probably not repairable.

The right side cup has a left handed thread. There is a chance that, if the cup wasn't forced all of the way in, that a shop could take the proper tap and chase down the threads.
