End of Life sympathy card

This has to be one of the hardest experiences to go through from both sides (and on a personal note, I am so sorry you are). Don't let them get away from you before you can tell them how much they mean to you. 

Card front reads:

What I want you to know as your time on earth grows short: I love you beyond compare, and when you're gone, I will miss you profoundly. I will never stop being grateful for the time we've spent together. When I'm listening to my favorite music, I will hear you in the song. When I see art that moves me, I will recognize you in the brushstrokes. When the stars are soft and bright, I will see you in the sky. When I am feeling happy, I will remember what if felt like to be with you, and I'll know you are watching over me. I want you to know you will be in my heart forever. 

Inside blank for your message.
