exactly.  
we have seen the day she turned and got banished but not the years and decades before that.  
and people can often feel guilt and shame even when it is not there fault.

“Same nightmare every night”  
So wait, at which time of day do you sleep, again?

@Jarkes  
What are headcanons?
 
Though, it’s not like there’s much more to speculate on or infer further. The well of What else happened? doesn’t exactly look fresh at this point.

@Tragiclady
 
There’s probably a LOT of stuff we don’t know about what happened that fateful night or what led to it.
 
And speaking of, I really hate it when people go, “If we didn’t see it, it didn’t happen.” Does no one know how to infer things that aren’t directly stated or shown based on things that ARE directly stated or shown anymore?

@Tragiclady  
“Quit feeling guilty about stuff/don’t beat yourself up over things” seems about right.

I was so glad that when Luna reappeared in season 2 she was a completely different character than the emo and angsty whiny Woona that became an half headcanon between the fandom.  
Now that finally they did a proper Luna episode after “eclipsed” they filled it with crawling in my skin bullshit.  
FUCK!

Other than trying to kill (fight? kidnap?) Celestia as Nightmare Moon, and trying to bring about eternal night, I’m not sure what shes feeling so guilty about.
 
She didn’t actually hurt anypony that I seen, other than her sister. And a thousand years on the moon seems a bit much for that.
 
I wonder if maybe this episode has a message I’m not getting. Other than quit feeling guilty about stuff/don’t beat yourself up over things.

I’m sorry Luna, but I can’t hear you over the sound of CRAAAAAWLING IN MY SKIIIIIIIIN THESE WOOOOOUNDS THEY WIIIIIIIL NOT HEEEEAAAAAAAAAL!

wow  
many angst

@5minuteswithapie  
Btw I didn’t mean you I meant Princess Wawa reason of why she created Tantabus.

@5minuteswithapie  

she has gone through immense amounts of hell, i can forgive her for this.

What a drama princess.

She is a very mentally damaged individual

@PonyPon  
*‘innocent people’ should probably read ‘former villains’

This is like inventing a robot to stab you while you sleep until you don’t feel like a bad person anymore, who then goes rogue and goes around stabbing everyone else.
 
Also, whomever thinks penalizing innocent people who have already proven remorseful is a good idea(you know who you are) I invite to rewatch this episode and see what that mentality can lead to.

TL;DR: Luna cuts herself.
