Life is so difficult.

It is very difficult to find a job in HK. Yesterday, I got an invitation to IMRE to have an interview. I was really happy. But today, I heard that my friend got blood cancer. How come!! She is so healthy. I can't believe. So what can I do for her? No, nothing I can do except praying. Another thing come to my mind is whether I should work aboard. If I got a cancer, will I regreted not treating my parent better, spending more time to them? I was really frustrating.
