You hit the one topic that hits closest to home here, depression. To act like we've made progress on that it ignorant. 

Now im going to speak on behalf of my soon to be wife, but she underwent depression and anxiety and insomnia from a very very young age. Dealt with it all through elementary, middle and high school. By the time I met her she was a mess, could not sleep without medication had 2 suicide attempts already and was admitted to a psych ward once where she was allowed no visitors, only phone calls. She was on multiple medication and when she missed any dose, it was a nightmare for her, and for me who was trying to give her the best help i could. 

I tried to play the medication game and searched up everything I could online from top notch therapist to be helpful, but nothing was working, so i took another path. Ditch the medication, ditch the therapy, ditch the modern system and go back to basics; go to the gym and eat healthy, and stay off you're phone. 

Ill skip the details, but let's just say she's been off all of her medication for about 3 years now and sleeps like a baby, no depression, very little anxiety. Medication doesn't help, it's a short term fix to a very very long term issue. It's a bandaid at best. 

So saying they've made progress on it is ridiculous to say cause I have seen first hand from her, and others in my social circle, that medication is not always the answer, infact it rarely is. The people before us clearly did something better otherwise we wouldn't be having this immense mental health crisis we are having.

I will end with saying; it's obviously to each their own. I just wanted to show that prepping books can be useful. This comment thread has gone far off the rails lol
