Hi Paulo, best wishes from the Netherlands. For most people, leading their daily lives with their daily worries and small problems, it is hard to understand what you are going through when a serious illness comes your way. I think this picture (from a website called XKCD) does a good job at explaining it:
All the people who posted in this thread, and many more SPers I am sure, hope to make you feel a little less alone in that awful grey area in the figure.
All the best wishes, and just know that, somewhere in the Netherlands, although we've never met, someone is a little worried for you too.
