I Am Struggling With My Faith

I'm sixteen, a christian and my faith isn't a strong as it used to be. I want it to be but I feel like I'm slipping. My family makes me feel bad almost every Sunday when we go to church which I think is helping me slip. Also certain things like the gay debate. I'm struggling with my sexuality and the church saying its wrong is not helping. I want it to be stronger so I've been doing more church things but I've never really felt a connection with God as others have. Any ideas.
