This is going to be an every day kind of thing for now. I’m pretty sure the Khan Core in Stage 1 is reprogramming you to believing you’re a King (which trust me, you are) but as it’s also clearing away all the shit from your beliefs it’s going to make you feel like crap also. One day you’ll feel amazing and the second day you’ll feel like shit, it is what it is.
Stage 2 will reprogram you with the real beliefs of being a King and someone no-one should fuck with. It’s the hardest Stage in my opinion but worth it. But trust me, anyone who’s ran Khan especially from what I’ve read has shared the same thoughts as you.
