Overcome life

I've never been this weak before. It's really suffering. These two days, what I did was just sleep, try to eat a little bit, vomit, go to toilet, and sleep again. Today when I fetched my son from school, the short distance was felt like miles away. I stopped few times before continued walking w/ my sis-in-law's son. Lucky I never faint on my way... Still feel quite weak but hopefully tomorrow I'll be able to go to work and do my job before stock take next Mon and Tue... Haiz... please help me, give me strength so that I can carry on my life and duty...
