Man, doesn't the last few lines just seem... oddly relatable? Phrases like "It's fine.. I'm perfectly fine..." or "I'm going to reset. This isn't like me at all..." just seem oddly relatable for some reason. It makes me question if the author is depressed.
From my POV (as someone who has these thoughts before and still do sometimes), it's a great coping mechanism if used properly. You get too heated in a silly argument? Remind yourself it isn't like you and calm down. Of course, the way she's doing it is not healthy at all, but what other choice does she have? I hope Chamii will stop any attempts at "you-know-what" if she does decides life isn't worth it.
