This sounds like it came from a place of fear. This is not an indictment, incidentally; just an observation. You choose language like "nuclear" and "destruction" and "lobotomise" and end with a plea to not make similar choices.

I'm in my forties. I have gone through multiple cycles of collecting and purging. How that feels has changed over the years. Sometimes I have regretted getting rid of some things, but that frequency is far, far lower than the number of times I haven't cared or even noticed. And those times I have regretted it have not resulted in obsessive thinking about what I've lost or what might have been.

Further, having a "reset" has proven valuable on more than one occasion, as it opens up new pathways that I might otherwise have not even considered. You speak of relearning everything as if it's forcing yourself to repeat the same path all over again, with no new learning and just a pointless sacrifice of what little time we have. In my experience, "relearning" usually entails discovering entirely new experiences and paths to knowledge along a general set of guidelines through half-memories.

To put it another way, starting over is not guaranteed suffering, it's an opportunity to discover new things.
