I am SO sorry to see you here, @Sabbra - but you have come to the right place for support and advice.
Where abouts are you (city or town/state) - as others may know of specific Breast Cancer help available in your town/state.
It sounds like you've had biopsies done but not necessarily the surgery?
Yes, the waiting really sucks! I know it will sound trite - but once the surgery has been done, mentally, it can become a lot 'easier' - fear of the unknown is what rules our brain at first diagnosis.
Put up any questions that you have - I am sure that someone with the same condition as you will give you valuable advice shortly.
In the mean time, all the best for your US & CT tomorrow - and try & keep as busy as you can until you know what the game plan is
take care xx
