My Life...My Sick...

I was sick for a week and still haven't recover yet.
Why my healthy is so weak?
What should i do to make it more better?
enough sleep? more exercise?
or... "he" is not be with me so everything bad thing happen to me?
I really don't like this type of feeling, when i started to go college and there is alot of thing happen to me especially my healthy..
sometimes I think of just end up my life and not to be suffer here, but I'm too selfish...
How was my family?
could someone tell me what I should do to make me more happier in life?
