First, what is your belief system that you would consider to be "permanently broken"? :) I doubt you'd make this thread if you did not wish to see it repaired if I can try to help you with it~ :)
Second, why is it broken? Have bad things been too much? Is sin/whatever similar concept your religion has been too much? Have you been convinced of a new belief system or convinced this one is wrong?
Nah, that's bunk. Christianity is what would be considered lukewarm water.

@timf replied with demonstrates a form of mere Christianity, a concept that takes Christianity back to its basics and implements those~ It abandons certain denominational beliefs that may trouble you while keeping the soul of Christianity~ It is not what Revelation 3:16 describes as "lukewarm" but rather still actively encourages doing good deeds based on one's faith rather than going along with everything the world says~ ofc, you could mean something else, and if you do, please tell me! ^_^
Have you been at a point in your life where you felt your faith was permanently broken?
Answering your initial question, no, I've never been at a place where it's been "permanently" broken~ It's cracked before, right when I joined this site actually as I suffered greatly at a church-related place I was at and began to have doubts that I couldn't quickly answer (shoddy internet). After reading Myotei's Dialogues, which directly countered the beliefs I was beginning to favor instead, restored it tho and further research myself has near completely discredited anything else.
