I personally agree that it could well be overexposure which could reduce cognitive functions. Having said that from experience sometimes certain subs did bring challenges into life. I am not saying the script in subs is harmful or anything like that, I am saying that the challenges are meant to be a tool to grow or a reminder of what we have been missing or ignoring. Alternatively sometimes a sub just is not compatible with one’s disposition.
Regardless what causes the worst luck/dropping things upon you, it sounds to me a psychological resistance/agitation towards Khan now exists in you due to the incidents. If this was the case and if I were you I’d stop listening to it, take a break to relax.
