News ?!?

How do you feel about the news? 
I just broke down crying my eyes out 
 
I grew up not watching the news my parents were against it & I just decided to not watch it because of the negativity I feel like it feeds on peoples fears & gives a negative outlook on life. 
I'm currently living with my grandparents all they do is wtch the news it doesn't really bother me to much I just leave the room but a year ago I got into a traumatic car accident and I was in the kitchen news was on & it was a bus crash on tv they showed the bus talked about how children passed I felt sick to my stomach and ran into my room and had an overwhelming feeling of sadness couldn't stop crying so bad to the point my mom had to come to the house and pick me up I had flash backs from my car wreck
What are your opinions on the news do you believe it's just negative or it's nessacary ?
