Catholics, should I convert?

I've went to Presbyterian Church my whole life, I never liked it. When I started going to a Catholic school, I went to my first m. Never being outside my parents' church before, I never knew how different it was. It actually felt like God was there, which I had never felt in my church. Our cl prayed the Rosary and I liked it. Even though I'm not Catholic, my teacher is making us all go to confession soon, but I don't think it will really do anything for me since I'm not a member of the RC church. My mom is against me becoming Catholic. Anytime I ask if we could go to a weekend m, she makes an excuse. It's just depressing to know that I'm going to graduate from the school this year, and won't be able to go to a church I like anymore. I keep praying that God will help me with this, but it's not working. We go over the beliefs in religion cl and so far I agree with the teachings, and also want a religion that requires more of a commitment. Either way, I'm going to convert when I'm old enough to drive to a different church. I just want to switch so bad.
