Unlike FK, I didn't need the "reparenting" aspect of therapy to challenge those beliefs. I was able to do that through cognitive therapy and a lot of practice, practice, practice at becoming deliberately conscious of when those beliefs were at play in my life, actively challenging myself to counter those beliefs, and repeatedly choosing to act on the corrected belief instead of defaulting to acting on the mistaken belief. It took a LOT of time and repetition to internalize new responses and more reasoned beliefs, but eventually I was able to get there, mostly because I became so completely determined to get beyond my past so I could enjoy my life now. For me it was a completely stubborn response. ( My T's have all commented on my tenacity. It's been a quality that has caused me problems at times and driven them a bit up the wall, but ultimately that stubbornness kept me alive and drove me toward healing.)
