theoretically the chain should have lasted you another good 10-15K miles or so but if you have been to late to save it then there is mothing you can do!
Just remember new chain means new sprokets as well (generally) as you will just shorten the life of the new chain. The spokets have already worn in against the old chain and will just grind against the new one with all there imperfections. (it sucks I know)
