I've done something bad, I feel horrible, and I will confess soon.
Here is the St. Faustina prayer.
"Help me oh Lord, that my eyes may be merciful so that I may never suspect or judge from appearances, but look for what is beautiful in my neighbors soul and come to their rescue.""Help me oh Lord that my ears may be merciful so that I give to my neighbors needs and not be indifferent to their pains and mourning.""Help me oh Lord that my tongue may be merciful so that I should never speak negatively of my neighbor, but have a word of comfort and forgiveness for all.""Help me oh Lord that my hands be merciful and be filled with good deeds so that I may do good onto my neighbors and take upon myself the more difficult tasks.""Help me oh Lord that my feet be merciful so that I may rush to assist my neighbor overcoming my own fatigue and weariness.""Help me oh Lord that my heart may be merciful so that I myself may feel all the sufferings of my neighbors, I will refuse my heart to no one, I will be sincere to those I know will abuse my kindness, and i will lock myself up in the most merciful heart of Jesus, I will bear my own suffering in silence, may Your mercy oh Lord rest upon me.
