Well, you certainly have plenty of advice here! But I will throw in my two coppers anyway.

Sometimes the reasons God calls us away from something we grew up with, is to help us to grow. I arrived at my current parish, almost 20 years ago (on and off, long story), with a mission on my heart. To bring the word of God to Deaf Catholics. I am Deaf myself, but I was able to gain a lot of the word and the bible in ways that many Deaf have no access to. The Churches of my childhood, I could never have been able to serve the way I do now, simply because they are not set up to serve the Deaf. Other churches I left, not because they were bad, or not Godly Biblical, but because I realized that my own presence there was causing problems. I come from a very casual farm girl back ground and wore slacks and very easy mellow attitude. The church we attended (my family and I) was very much a strong on the go, city living, FAST paced life. Oh, and women were expected to be WOMEN. Well I am a woman, but I tend to be high on the side of practical and having two young boys (one whom was in the "throw up mommy's dress stage") kept me in slacks for a while.

So we quietly stepped out and moved on. Was it because of feelings? No, because of biblical reasons, our presence was putting stones in their paths.

So, ask God in Prayer, if you need to be a missionary for a bit, to learn where he wants you to serve. What are your talents? What has he called you to do? It not always so clear cut. It is very normal that the children that grew up in one church, tend to move on to other churches having needs of their talents that might not be used where they are.

My prayers are with you.

I can understand feeling like it's just your family's church & you're not able to make the strong connections you need.  I would recommend following your convictions & looking elsewhere, only after you've talked with your parents so that it doesn't blind-side them.

Also, if you have been really involved in volunteering there, you can still keep informed through your family about what may be needed and show up to help occasionally, to keep gossip down & keep up relationships with people that you don't want to leave behind.  My brother started leading worship at our family's old church, and they were always happy to see the rest of us when we showed up to help him or to do other things with the church.  When there are healthy relationships, I've found this can be a really good way of making it a pleasant transition.

I think all the advice above has been great and really interesting......so I don't have any advice for you.  However, I can tell you that I think to leave will be worth it despite all the possible negative emotions by others.

My family went to the same church for my whole life.  (and well before my life began)  Every person there was like family, and actually the pastor was family.  When we realized it was time for us to move on, it was an extremely difficult decision.  It was hard for us and it was confusing to people who had known us forever. 

It wasn't easy.  It still isn't sometimes.  But here's what I can tell you.  When you find the right place, it's worth it all!!  We found somewhere so amazing that I still can't believe it sometimes.  It was like we experienced personal revival in each of our lives....    It's so awesome when you can be excited about church again, and know that you will grow there and be able to help others grow.  I don't know how to explain it other than awesome.  Difficult? yes!  Worth it?  Yes Yes Yes!!!!
