Christian or Catholic?

I love God, literally. And I was born a Catholic. And I am in a Catholic school. My aunt is somewhat, a Christian, which is somehow, the same (both Jesus believer) but the teachings are kinda different. And they told me about the wrong teachings in Catholic, which is kinda true and they kinda want me to go to their church which is, I don't find reasonable at all. I would like to keep my faith and belief in Catholic but I don't know if it is right. Or maybe go to Christian? I really don't know. I keep telling myself that it doesn't matter as long as you love and have faith with the Lord but I still have to pick my church. Please share your opinions with this.
