Hi Niki,
I just recently went back to church after being gone for just as many years. If you don't know anyone in the ward look for the missionaries and sit with them, the church has Sacrament every Sunday now. Also since I was away for so long I attend the Gospel Principles class. After being gone for so long I need a refresher and this class fits the bill. Ask the teacher if you can keep your book so you can study it at home. After that you'll go to Relief Society and that is very enjoyable. At some point you will want to introduce yourself to the Bishop. Don't be scared he will be glad to meet you. Welcome home Niki.
