Doctors can't cure T. So what are they supposed to say? Even to provide support to T-sufferers, that they will be able to benefit from, may requiere a special understanding of and knowledge about the condition, perhaps even a specifik talent for communication as well. Chronical medical conditions is a bitch.
With T, you're on your own. There are some paths that can be tried out, but they will depend on individual thinking, ability and research. Getting angry on doctors indicates an inclination to depend on them, which in my opinion is utterly pointless.
