I don't have direct experience of your predicament, and am presuming that you were born into a Catholic church going family. So, in a way, this was never your choice - you just continued family tradition.
Now you are older you realise that maybe it isn't quite what you want or need. That seems perfectly reasonable to me and I think we all deserve to worship in whatever way feels most meaningful and helpful to us.
Our faith (if we have one) should enhance our lives and give us peace, support, and comfort. I do know a Church of Scotland minister who "converted" from RC, and he was a much respected leader of his congregation and helped many people through their doubts and uncertainties.
