How?

Not sure exactly how, because it was quite easy actually. It answered so many questions, and kind of provided the image for the puzzle I struggled to put together for the 10 yrs prior to being dxd.

Relieved much?

I was like, "I knew it! I am crazy! Atleast now I know what kind of crazy!!"

Not only that, but for me, knowledge is empowering, so knowing and accepting it, helps me obtain a better quality of life.
To me it just made sense to do so, because the alternative would be like denying I have a broken leg, struggling to walk normally, wondering why I can't walk, and then complaining about the excrutiating pain I'm in which means I am ultimately complicating my own life, and compromising my quality of life in the process.

Just didn't make sense for me to deny it,and I'm pedantic about me making sense.
