One example of how this mindset worked for me is probably best demonstrated by my experience with sleep paralysis. My anxiety kept me tossing and turning in bed, and I would eventually fall unconscious due to exhaustion - triggering sleep paralysis. I of course developed fear of sleep paralysis and thus going to bed made me anxious... cue vicious cycle.
How did I break the cycle? I had to develop a joy for sleep paralysis. A genuine interest and joy for that experience. Once I started to look forward to it, the vicious cycle was broken and I no longer got sleep paralysis. It was the ultimate reframe. I psyched myself out.
I eventually started to apply that same principal to other anxieties and insecurities and things just started to melt away.
A vicious cycle of sleep paralysis is pit of hell though. I don't recommend it.
