Will I go completely insane ?

Hi guys, I don't why but recently I felt a urge to replay the OG SCP CB and I want to do something.

I would like to play the game in ketter difficulty (wich I have never done) and get every achievements. However even if I played a lot of this game I'm scared that this challenge will fucking drive me crazy.

I already did a full achievements run in Euclid wich was a lot of fun and I did a few speedrun of the game however I haven't played it in years.
