Do not allow the negative drown the positive. The positive qualities about you can shine so bright that it blinds the Evil that claws at you. The voices that are telling you that you are worthless and useless are uncreative and weak compared to the strength that keeps you going every single day, every single hour, every single minute, every single second. 

"Are not two sparrows sold for a penny? Yet not one of them will fall to the ground outside your Father's care. And even the very hairs of your head are all numbered. SO, DON'T BE AFRAID; YOU ARE WORTH MORE THAN MANY SPARROWS." - Matthew 10:29-31

You are so worth it that I, some random girl on the internet, has been called to tell you so. Every pain that you are going through is just going to make you stronger. You are beautiful. You are enough. You always have been. You always will be. Your bright and hopeful future is worth every tear you may shed right now. You will move mountains. You are important in ways that you (or I) can't even comprehend because you have such a special place in this puzzle that is life. 

You are so worth it that someone went through hell and came out the other side with just His love for you pulling him through. If someone is worth going through hell for you, then you are definately worth it.
