Will I go to hell for leaving the Catholic church?

I'm looking for some answers. I have been raised my whole life in the Catholic church. My dad is very Catholic, I go to M nearly every week, and I had catechism cles for many years and have been confirmed. I don't really want to be Catholic anymore though. I find that most Catholics I have talked to are very judgmental and condescending towards other people, which is very far from the message that Jesus preached. If I decide not to consider myself Catholic anymore, will I go to hell? I believe very strongly in God and Jesus and that Jesus was God's son and that he died and went to hell for us. I believe that Jesus is present in the Eucharist through the power that is the Holy Spirit that flows through all of us. My faith is not shaken in the least. It is, in fact, stronger now than it has every been. I am just not spiritually fulfilled by the Catholic church anymore. If I don't go to a church and just worship on my own time, in my own way, is that a sin? If so how can you say that I will go to hell for believing in Jesus? I do not like the idea that one denomination of Christians is right and all others are wrong. It seems very contradictory to what Jesus taught us. Jesus preached a message of love and compion towards our fellow man, and that is how I try to live my life. But I have been raised to think that that's not enough. That I have to strictly follow all the rules of the Catholic church if I am to go to heaven. Is it not enough to follow Jesus and try to live how He would want me to? It is all very confusing, any views you have or explanations would be greatly appreciated.
