I agree with what Inertia said.

To add to it, maybe try doing some research when you are ready to find out exactly what everything means.
A lot of information is given in statistical form which doesn't help when YOU are the one facing everything so if you researched what everything is not only will it help you to better understand it in a round about way it helps you prepare mentally for what lies ahead.

I am so sorry you are facing such a difficult time,my advice is to just take each day as it comes, the good the bad and the down right devastating. There is no right or wrong reaction.

As for the people saying stuff - Unless you have been in a situation like this there is absolutely no way they can understand. It doesn't make hurtful comments better but from my experience telling myself that they are only saying things to try to help or to understand what I am going through can help a little.

People often don't know how to help and really its all they are trying to do you just have to bite your lip at the time then let out all your frustrations in here
