I guess you are :) . I will tell you a secret. I suspect I'm a Chinese room too ^^ ...
There are also people with so called total locked-in syndrome i.e. people who can not do any voluntary movements even with their eyes, so there is no way to communicate with them. How would you decide if they are conscious? It may be literally matter of live and death for them. How should we know if they even want to live in their condition?
You may be even a biological human and I still won't know if you are a Chinese room.
Maybe since birth you are just sort of sleepwalking? I wouldn't be surprised if there were fully functional people without qualia.
