Johns Journal
5^th of July 1899.

I woke up this morning with an indescribable headache. I was lying on the floor in the nursery. At that point, I really didn’t remember what had happened last day, until I saw the yellow wallpaper that had been ripped of the wall. Yesterdays happenings reviewed in my shaken head. It was terrible, I passed out again.

When I woke up this time, my thoughts where a bit clearer, even though I still found it hard to believe. My wife has gone totally insane.

When I fist tried to enter the nursery where she were, the door was locked. I kindly asked her to open the door but evidently she had thrown the key out of the window. When I finally came in, I saw the craziest thing I ever seen. My wife were creeping around in circles on the floor over what she called another woman, and tried to rip all the wallpaper of the wall at the same time as she was making strange noises. I couldn’t understand what I saw, it was so macabre and just too much, I fainted.

My afterwards thoughts were that I should have predicted this earlier. She has been mentally ill for some months now and it has just getting worse and worse, even though I told her the opposite. I really did what was the best for her; I even rented a house for her sake, with a room that perfectly fitted her needs. I have for a pretty long time seen signs of mentally problems with her, and I’ve since then tried to help her. What she needed was to be for herself for a while, too take long walks in the forest and just try to recover, and what did I get for that? A wife that creeps like a total maniac on the floor. I have now realized that there is no hope in her case, not at all. I can’t take care of someone that not appreciates everything I do for her, and never recover, that’s why I think her case is hopeless. I actually even question myself and my own method, to try to heal her mentally illness. It was at that point I realized that the whole thing has went to far. I’m not the one who’s having mentally problems. I’m even a doctor so I really knows what’s best for her, but the thing is, she didn’t do as I told her. And that’s why the whole thing just blow over. I told her to not think too much, to not read or write but she did it anyway, no doubt that she never recovered and went better.

I’m an educated man with lots of experience of these types of cases and I’ve never seen anything like this, that’s why I’m so sure that she did this to herself.
By the way - I found her diary yesterday. I read it a few times and you don’t even have to be a doctor to see that this is the main factor for her deterioration.

I’ll now go further in my life without my wife. She’ll in a few minutes go to a mental hospital near this place and I will go further in my life with a good conscience…
