The proverbial "leap of faith" is actually the size of a mustard seed. Keep going. And by the way, look at St. Augustine. Don't become disheartened that you made bad choices in the past; make the best choice you ever made by turning to the Lord-- watch as the Lord, through the Sacraments, reorients your life and puts a lot of broken pieces back together.
"One thing have I desired of the Lord, that will I seek after; that I may dwell in the house of the Lord all the days of my life, to behold the beauty of the Lord, and to enquire in his temple." Psalm 27:4
