Analysis of My sister's birthday is almost here again!!!!

My sister's birthday is almost here again.
I haven't been this happy in I don't know when.

She is the epitome of everything that I love.
She was given to me by our God above.

She never seems to know her worth inside.
I will forever be with her, right by her side.

She's my ray of sunshine, she's there to light my way.
She helps me make it through, even on my worst day.

Her smile is beautiful, just like her soul.
She is the reason, I fight to stay whole.

She gives me the drive to accept all my faults.
She inspires me to not keep it locked up in vaults.

To just let it go and let my feelings out, through my poetry.
She may be my little sister, but she's always teaching me.

I swear she is my identical twin, a mirror image of me.
Sometimes it's hard to tell if it's her or me that I see.

The brave, incredible woman, she turned out to be.
She was sent to this earth, to keep me company.

When I look at her, she gives me the hope that I need.
To lead a good life, be happy, and let myself be freed.
