That really is a cruel hing to happen at such a young age.It isnt the reason I,m came here and a good few years ago now, but i lost a partner aged 30 to cancer.
You will in time come to realise that you did not fail her but i understand that feeling all too well, and that even with all the odds stacked against them and all the knowledge of that in your head it is still a shock when that last minute miracle actually doesnt happen.
Back then there was no-where like this to come for help but it has been a real help to me in my more recent loss.We are here to support you and one day you may find you are helping others without even thinking about it just by mutual discussion, there really is no expectation or pressure, we are all at different stages of what i,m afraid can be a long and unpleasant journey but one we all share and that sharing makes us stronger.
