real too good for this sub. How do I (28m) help my girlfriend (26f) overcome her guilty fetish/guilt kink?

Title says it all. I've done my own research and it seems this may have something to do with CBT? How do I help her overcome this and what are the next steps?<br><br>for anyone that decides to make a medical diagnosis, please don't.<br><br>EDIT: I know this sub is all about incest and the description says it all, but I assure you this is not about incest.
