How do I keep the Faith in this situation and bear the light of Christ?

I am on my school debate team and surrounded by those who have left the Faith, distorted it, or spend their time trying to undermine it through argument. My coaches look at my mom like she grew a third eye when she pulls me from a debate competition early to take me to Mass. Someone who claims to be Catholic on the team asserts the position that truth is relative, ect. In addition to this, one of my teachers claims to be Catholic and uses his European history lectures to insult the Holy Catholic Church. The result for me has been confusion and a crisis of faith, along with the blending of Religious and political arguments. I try to hold my own against this through argument, and it has taught me to take a closer look at things related to doctrine. Almost always, though I have trouble choosing my battles and engage in unnecessary argument, to the point that team members know not to engage in religious debate with me, or do so for laughs.:mad: Success has brought me closer to God through the Most Holy Rosary (I prayed the Most Holy Rosary for success and that is what I got :thumbsup:), but at the same time it has thrown me further into a crisis of faith. At confession, I confessed that I had lost faith almost completely, and the Priest told me to take it almost as a Blessing or Gift that led me to research further and see all the successful individuals throughout the history of the Holy Roman Catholic Church. I am convinced God has opened a door for me, because it was a string of complicated events that led me to join the particular part of the team that I am on. Coincidence does not exist, and I am sure this was Christ opening a door for me. My judgment is clouded, however, by the fact that the girl I kinda like is on the team (she is a true Catholic btw :thumbsup:). How do I let Christ shine through me and represent the Catholic Faith in this situation?

I will ask that our Good Lord and Savior Jesus Christ Bless you for reading this, Thank you.
