I have one similar to the top one except I designed it myself put somethings in it to reflect who I am.
I pray for you, my mother is going through cancer right now, and they removed half of her left lung.
My advice to you is pick what you feel is the best for your beliefs. Follow your heart.. And if you find it too hard to choose.. put one over your heart one on you back and cover your coming and goings.
It's just my opinion and nothing more.
