Thanks for the replies.
Sounds like you and I have run a similar path Kerryn - I was also diagnosed at 26, am 27 now and no children. I've worked full time through the whole experience. I'm in the radiotherapy waiting room as we speak before I head into work again today.
I've had more than ample support from the offline world, but my post was more food for thought so that users might be more considerate of those who do turn to the online world for support. There are plenty of other groups on here where older ladies can post their blogs or whatever.
