hey hey
I'm sorry to read that you are sad. Cheer up, girl...you have a God on your side who will never ever leave you or forsake you. He says so Himself many times all throughout the Bible, in both the Old and New Testament. No joke.
Joshua 1:5 ...so I will be with thee: I will not fail thee, nor forsake thee Hebrews 13:5 . . . God has said, “Never will I leave you; never will I forsake you.” There's soo many more! Here are just some more (Genesis 28:15; Deuteronomy 4:31; Deuteronomy 31:6; Deuteronomy 31:8; Psalms 9:10; Isaiah 41:17; Matthew 28:20; 2 Corinthians 4:8...)
Keep trusting in God. He sees your sadness. He hasn't forgotten you! Here's a song that I personally find a source of comfort in when I'm sad:
"He Will Carry Me"
Mark Schultz
I call, You hear me
I've lost it all
And it's more then I can bear
I feel so empty
Your strong, I'm weary
I'm holding on
But I feel like giving in
But still You're with me
And even though I'm walking
Through the valley of the shadow
I will hold tight to the hand of Him
Who's love will comfort me
And when my hope is gone
And I've been wounded in the battle
He is all the strength that I will ever need
He will carry me
I know I'm broken
But You alone
Can mend this heart of mine
Your always with me
And even though I feel so lonely
Like I have never been before
You never said it would be easy
But You said You'd see me through the storm
You are never alone! I pray that He will turn your this: 
into this:
