Welcome. I hope you find hope and comfort as you continue in your search for truth. It is good that you are reading In Search of Christian Freedom but you would also be well served by reading Crisis of Conscience as soon as possible, too.
As one who has been where you are, I would encourage you not to say ANYthing about your questions or doubts. Voice them here, where you will be welcome and get them off your chest safely.
Stick with the quest for freedom of mind and REAL accurate knowledge and you will be fine.
