The mother dies because his father hits her every day and strips her down the steps. 

I'm OK

Once upon a time there was a girl
In her early years she had to learn
How to grow up living in a war that she called home
Never know just where to turn for shelter from the storm
Hurt me to see the pain across my mother's face
Everytime my father's fist would put her in her place
Hearing all the yelling I would cry up in my room
Hoping it would be over soon

Bruises fade father, but the pain remains the same
And I still remember how you kept me so afraid
Strength is my mother for all the love she gave
Every morning that I wake I look back to yesterday
And I'm OK

I often wonder why I carry all this guilt
When it's you that helped me put up all these walls I've built
Shadows stir at night through a crack in the door
The echo of a broken child screaming "please no more"
Daddy, don't you understand the damage you have done
To you it's just a memory, but for me it still lives on

Bruises fade father, but the pain remains the same
And I still remember how you kept me so, so afraid
Strength is my mother for all the love she gave
Every morning that I wake I look back to yesterday

It's not so easy to forget
All the lines you left along her neck
When I was thrown against cold stairs
And every day I'm afraid to come home
In fear of what I might see there

Bruises fade father but the pain remains the same
And I still remember how you kept me so afraid
Strength is my mother for all the love she gave
Every morning that I wake I look back to yesterday
And I'm OK
I'm O

Study links chocolate and depression

One need only look at the recent introduction of chocolate Cheerios to fully grasp Americans' fondness for the pulp from cacao beans. Savoring chocolate is normal.

But, researchers said Monday, overindulging in it could be a marker for depression.

Researchers at UC San Diego and UC Davis examined chocolate consumption and other dietary intake patterns among 931 men and women who were not using antidepressants. The participants were also given a depression screening test. Those who screened positive for possible depression consumed an average of 8.4 servings of chocolate — defined as one ounce of chocolate candy — per month. That compared with 5.4 servings per month among people who were not depressed.

Those who scored highest on the mood tests, indicating possible major depression, consumed an average of 11.8 servings per month. The findings were similar among women and men.

When the researchers controlled for other dietary factors that could be linked to mood — such as caffeine, fat and carbohydrate intake — they found only chocolate consumption correlated with mood.

It's not clear how the two are linked, the authors wrote. It could be that depression stimulates chocolate cravings as a form of self-treatment. Chocolate prompts the release of certain chemicals in the brain, such as dopamine, that produce feelings of pleasure.

SUMMARY 

Everybody likes chocolate, but overindulging in it, could make you depressed.  Researchers investigated with people, and the ones who had depression consumed an average of 8.4 servings of chocolate. They also tried to find more meals linked with the mood but they found nothing. Chocolate prompt the release of chemicals –such as dopamine-  in the brain which produces feelings of pleasure.
