In 1913 I had a dreadful fever. At this time Our Lord was calling me to Himself but I didn’t take notice of His voice.
Then last year  I got appendicitis, and this made me hear His dear voice that was calling me to make me His spouse later on in Carmel. […]
Every day my pains and illness became worse. On the 8th of December, I felt I was going to die. From that day I remained in bed until I was able to get up after my operation.
It was decided that I had to have the operation. On Monday the 28th they rented a room in Saint Vincent’s. Only God knows what I suffered. It gave me great pain to think of dying outside my home.
On the other hand, I felt such great repugnance to sleeping in beds where other sick people have been…. Thus it is that I felt horrible in going.
On Monday I went by car with my mother and my mamita to the hospital. I was almost dead from fatigue when I arrived at my room in Saint Vincent’s, but then I recovered.
At 5:00 in the morning, I went to Communion. How beautiful that Communion was! I believed it was to be my last.
With all my soul I asked our Lord that he would give me courage and serenity. What would have become of me without the help of Jesus? Oh, my most sweet Jesus, I love You!
Later the nurse came to prepare me. Then the doctors, etc.
After lunch, my nerves were so bad that I didn’t know what was happening to me and I began to cry and laugh. My mother gave me some medicine and I remained very calm. […] I was preparing to die.
Saint Teresa of the Andes
Her intimate spiritual diary
Chapters 8, excerpts
Note: St. Teresa of the Andes had an emergency appendectomy on 28 December 1914, a procedure that entailed great risk. The only anesthetic available at that time was chloroform. Because of the risk involved, Teresa approached the procedure with mixed emotions and faith: great fear, uncontrollable laughter, deep grief, boundless trust, and limitless love.
