I am so sorry...you know, I used to feel the way you do. A little awkward and unsure of what to say. Please forgive yourself for that, for me that didn't change until I was in my late 30's as more and more people I knew fell ill and passed away.
One thing I learned from my friend was to not be afraid of speaking of the person who is ill or has passed away. Sharing funny memories...loving memories...and such always bring comfort to those of us left behind.
Now...make sure you contact your aunt on a regular basis, be willing to listen as she grieves and dare to grieve with her.
I hope this helps you...know that I will keep you and your family in my prayers.
