L.H.
I go to a more contemporary church on William Blount Drive, Cedar Point. It's non-denominational and very upbeat. It has a wonderful childrens program and everyone is super nice.
Service starts at 10:30A and if you want you can visit the website... http://cedarpointmaryville.org/
I have just recently began going back to church and this if the firt church where I didnt feel completely out of place. This coming Sunday would be great time for you to visit we are having a church picnic after service. Everyone has been asked to bring a side dish or dessert and I think it will be a great way to get to know the others at the church.
Good luck! I know how hard this can be...
