Religion

Does one have to attend a house of worship to be religious? I believe that one can find religion in their own way and their own manor. They don't have to be guided by the strict structure of organized religion. For example, I believe in Jesus and I considered myself to be Catholic. However, I have not been to church or any real religious service in about 15 years. I do believe that Jesus was the son of Christ and that he is our savior but with no real religious background. Does this make me a hypocrite?
