The video montage chronicles Diem's extraordinary life, from her birth in Germany to her Florida State University sorority days and stints on MTV's The Challenge, where many first fell in love with her vibrant personality, positive attitude and fun-loving spirit.
The tribute also features photos of the vivacious reality star and reporter throughout her multiple struggles with ovarian cancer, always with a smile on her face and positive attitude.
"Don't take any moment for granted," the MedGift founder urges. "Just go for it, do it."
Diem, who loved dancing and holidays, passed away on Nov. 14 during her third battle with cancer and was remembered by her Challenge castmate and longtime love CT Tamburello in a sweet Instagram post.
You have always been My Angel. And now you have your wings. We've been thru so much over the years. Thru the ups and downs we somehow managed to keep our promise. We never gave up on each other. Our plan to be together forever hasn't changed... it's just going to take a little longer now. And I'm going to hold onto this ring for you till we are together again. So don't worry mama, I'm not afraid. I know you will always be with me to give me your strength. You are The Love of My Life. My reason to be a better man. I Love You Always and Forever
R.I.P., Diem, and thank you for inspiring us with your endless light and infectious love for life.
