If I can add my opinion on the residential treatment place - I did one when I was 18 and I was there for roughly 5 months or so. I was also probably in the most severe episode of depression of my life, and I needed ECT, and all of that. They basically got me out of there and I was not that great, but I was okay, and that was better than I entered the place feeling.

So, I guess, if you have reasonable expectations about it - it can improve your mental state, for sure. I understand that my experience is probably different than other people's in terms of the time frame I spent there - I mean 5 months is a super long time.

Anyway, yeah, I wish depression and psychosis were easier to treat, but they're really not that easy to treat. Luckily, I'm on a pretty good combination of meds right now, it's just the outside stuff that I need work on - I am planning on joining a DBT group, for example. Just because meeting with people going through similar stuff w. a therapist is helpful to me.
