Other than Bart Ehrman, one book that really helped me to get over the guilt was Helping Jesus Fulfill Prophecy by Robert Miller.
Basically points out all the ways the Gospel writers twist scriptures and ignore context in order to make it seems like Jesus fulfilled prophecies, in many cases it's hard to conclude that it wasn't willful deception.
Once you realize the authors of the Bible were relying on deception to promote their beliefs, it becomes really hard to take any of their other claims seriously. Surely an actual God could have done better.
