This is most heartbreaking. I mean, I could tell from your other thread that something serious was going on, but I'd never have imagined that things would be this bad. x_x
That said, there's always hope--probably more so than you think right now. I've taken a look at the survival rate data, and it seems to be compiled from over 20 years ago. Science and cancer treatment medicine has improved since then. Those rates are also averages, and account for a majority of patients likely being older people, whose chances of survival are significantly less than those of a younger patient like yourself. As a Mabinogi expert, you should know well that %s suck and you can't ever depend on them. D:<
And more importantly, you're not average, period. Just think back on your life, and how many problems you've managed to overcome and survive. If you could survive the death by reptile, you'll survive this!
Then there's your energetic outlook on life in general. It's like your secret weapon--don't ever lose it! As long as you stay strong in spirit, your chances of recovery will be good.
I really wish there was something I could do to help. I don't know if god exists, but I'll be praying for your recovery.
