Do you have to go to Church to be a "true" believer?

I am asking Christians only, in your minds do you have to attend church to be a true Christian/believer of Jesus Christ and God? I ask because I do not attend church but I believe in God and would definitely say I am a Christian but someone recently said I was not showing that to be true because if I did, I  would go to church. My opinion is that I don't like what churches have become and I feel I can serve my god from anywhere.
