Prayer of St. Faustina

"I must be on my guard, especially today, because I am becoming over-sensitive to everything. Things I would not pay any attention to when I am healthy bother me today. O my Jesus, my shield and my strength, grant me Your grace that I may emerge victorious from these combats. O my Jesus, transform me into Yourself by the power of Your love, that I may be a worthy tool in proclaiming Your mercy."
