Can You Explain?

I'm at the point where everything in my life just crashed.
My stupid younger sister got pregnant
My mother said she was to young to get pregnant,
So she'll raise her baby as her own.
I am so confused.
Why did you care more for her when she was pregnant, but not with me?
She is just a year younger!
Why did you go to the hospital when she had her baby and not when I lost mine?
I still don't get it.
Can you explain??
So many fucken questions I have kept inside.
I still can't find a way to ask you them because it hurts so much.
I guess the answer is because I am a big disappointment.
Since you care more about anyone other than me.
At least I have found one answer for most of my fucken question.
