I agree completely with Sam, things happen for a reason.
I have no idea what you must be going through Rach, but even though you must feel on your own, you are not. That is what we are all here for. The support I have found on here for those 'down days' is invaluable.
You also already have a child, and I'm sure he (I seem to remember he's a boy) is at an age where he can help you.
I want to shout 'congratulations' at you, but I know your head must be all over the place at the minute, so that may be the wrong word to use today. However I am sure that you will come to terms with this, and realise that you will all be okay.
Sending you lots of Hugs.
