To my unbelievably beautiful mama,Thank you.

Thank you for fighting as hard as you did for as long as you did.

Thank you for raising me to love Jesus, and show that love to others.

That’s something you did so well.

But I know you’re watching over me.

Although it hurts me so bad to watch you go, I’m so happy you are happy again.

I’m happy you get to be with Jesus, and see your dad.

I’m happy you aren’t in pain anymore.

I’m happy I got to have these past few months with you.

I loved taking care of you.

You’ll always be my favorite patient.

I love you to heaven and back a million times.

I know one day we will meet again.

Until then, I’ll spend every minute missing you, and trying to make you proud.
