I was raised Catholic up until 12 years old, then my parents became jw. Was a witness until 48, but during this time I could never stomach all of their teachings. And I remember that when you don't follow every belief, teaching, according to the jw way of thinking, there is something wrong with your spirituality.
When I walked away, I dealt with the same dilemma you are experiencing. I looked at other religions, and on my own studied what they believed, ( warning please don't join a free study or anything along that line). I noticed how each religion attempted to mold me into their line of thinking.
So at this point I have gone full circle. I attend Catholic services occasionally, and have gotten involved in several of their volunteer endeavors such as helping children dealing with problems, assisting elderly ones , and by experiencing the results from these opportunities I'm learning to develop my own personal relationship with God. Being spiritual I've discovered is something that comes from an individuals heart, not someone telling me what to do. Being involved to a certain extent with a religion helps keep me focused on what is important in life. Ceremonies, prayer, and readings pull me back to what I grew up with and make me realize what is important to me. Getting involved 110% like the witnesses way of living did was just so wrong, developing my own relationship with God is a wonderful thing. Good luck with your journey !
