Hi Christina,
CJF is right, the next few weeks and months even will be really different, after all your world has just been turned upside down. Once the extent of the cancer is quantified and the treatment options, presented then it starts to settle down a little, because suddenly we are back in some sort of control of life.
I had Endo cancer 9 1/2 yrs ago... I also was miles away from any family who could really help, but somehow you learn to cope with the resources available, you will amaze yourself at your inner strength, but make sure you rest when you can and most of all be kind to yourself.
Everyone has a different experience of cancer and treatment, but we nearly all say our attitude to life changes, it highlights the really important things in life.
Go well and if you need to "talk", we're here to listen.
Rgds, Sam
