I'm sorry to hear that. It is a pain. Even I myself struggled with it.
It was a game design decision I made because of my inexperience when I worked on that version. It would change in the next version.
Oh, I was talking about the game too, not an actual depression (now I'm really sorry).
Because I myself struggle with the game (I do play my own game). And while I realized it was hard, I like the challenge and decided not to dwell on it and put it on the list of things to be added for the next version.
So, yeah the next v.0.1 has a different mechanic than v.0.0.6 for Mental State. Hopefully you will like the change.
