I'm rubbish at 'being supportive' (in the emotional sense), so I won't even try. (NB: That doesn't mean I don't care!!!)
However the doctors either won't have provided you with all of the facts or you'll have simply been too confused to take them all in. So I'll provide this link to the NHS website, which is packed with information.
http://www.nhs.uk/con...ges/Introduction.aspx
Click through the various links (e.g. 'Treatment' and 'Living with, and play the videos, to get a better understanding of your condition).
If you need someone to talk to, pick up the phone tomorrow evening:
http://www.jostrust.org.uk/support/helpline
or call Macmillan on any weekday:
http://www.macmillan....elp/HowWeCanHelp.aspx
(Note that you can enter your postcode, at the foot of that page, to find a local support group).
In the meantime tell yourself that you're still going to enjoy Christmas - because you bloody well deserve it!
With best wishes,
Chris
