Do you think I will go to Heaven?

I've accepted Jesus as my Savoir and I love God too. I'm not perfect, far from it but I do try to get along with people and I am kind to others. My down side is that I still use profanity from time to time and I don't always go to church like I should. I do try to pray every day and Jesus is still in my heart. I worry that I won't get there though because I was told I could lose my salvation. It's hard trying to be perfect. I wonder every day if I am doing something that is not good in God's eyes such as listening to rock-n roll and rap but I do also listen to Christian music. I'm just wondering that there might be a sin that I haven't asked for forgiveness for and God won't let me in. Sorry this is so long, but it's really bothering me.
