How Can I Become A Priest?

I am a 13 year old boy, and have found enlightenment in Catholicism, my cousin became a priest last year and ever since that is what I have aspired to be. The only problem is, I haven't been going to church because my mother thinks it is silly and strictly forbids me from going, so I have been frightened I wont be able to become a priest because I dont have access to the Church. Because I dont go to church, I have bought a bible and started to pray on my own. Please give me some advice. God Bless.
