It doesn't really matter exactly what you do, as long as you are doing something to serve in a way you feel is important and meaningful.
So, pick something about which you can feel passionate - or about which your family can feel passionate as they serve with you.
Who knows? Maybe your faith crisis was God's way of prompting you to have an impact on a greater scale than you could have had solely in a leadership position in the Church - and maybe, just maybe, it will turn you into someone who actually can provide leadership on a broader scale in the Church in the future, since it might help you understand better others who struggle for whatever reason. I don't care about that as much as what you can do in the here and now, since I believe what you can do in the future will be influenced greatly by what you do in the here and now. So, find a passion now and do it.
