Just wanted to add here that I'm also Roman Catholic, a convert from a Pentecostal church. The DRE at my parish is one of the first people I came out to as bisexual. She was and is very supportive. I just wanted you to know, Snoopy, that there are supportive people in the Catholic church out there. I will certainly be praying for you.
"Beloved let us tolerate one another. For tolerance is of God and everyone that tolerates is born of God and knows God. He that tolerates not, knows not God for God is tolerance." 1 John 4:7,8
