Keep reading the main CA page to get your apologetics down. You want to KNOW where in the bible to show them why we do things. Practice your responses. Get comfortable with sharing the faith. Read a lot, and pray a lot, especially before the Blessed Sacrament.
I know how hard it is, I’m a convert myself. Ground yourself in knowledge, and stay close to Jesus through prayer. The one thing I kept coming back to with my family was, “This is where God is leading me, and I have to follow Him. How can I deny what God is calling me to?” Good luck, and we’ll pray for you!
