beginning noob-y bamboo help

Hi, I'm not sure if I possibly killed my indoor bamboo plant five minutes ago. A branch was corn-yellow and decaying, all of it not just one layer so I tried to cut it off, but I accidently took some of the healthy part with it and I'm worried if my plant will now start decaying and rotting as a whole (which happened to another one). But the rest are really green and healthy. Help, please? I'd like post a photo but the image thing isn't cooperating.
