Welcome and I personally think that you probably don't wanna tell that to anybody at this stage, since you're newly diagnosed and you're being scared of the diagnosis. The diagnosis should be helping you to understand about yourself instead, by understanding what it is about, what sort of treatment options there are, and how much is it gonna cost? etc... Some informations about the diagnosis quite honestly should scare you to some degrees, the truth is not so clearcut until you get the sufficient evidence to believe in what has been said/presented to you.

In the mean time, you could try to relax. (the truth have no guarantee for the relaxed time, we need to work for it sometimes, like meditations, soothing music, exercise, proper sleeping schedule which I don't care much for, my point is, doctors don't have the time to tell you everything, you get the knowledge for yourself with the support from members from here or elsewhere, and people come here from all walks of life, please don't forget to take a look around at all other parts of this forum and I hope you find something interesting there as well.)

Knowledge is the power, gaining it and the understanding it may take some time. Best wishes to you for your study and staying you.
