Spirituality and religion are not the same thing, sounds like you are talking about religious experience.

I did hear voices, see things etc..psychosis NOS is one of my dx's. I didnt learn to live with it. As I got well it went away with it, which makes sense. Voices are you, your brain is creating it, and if it is creating it it can also do the opposite and not create it.

But you have to want to get better, you have to hope, and you have to leave doors to possibilities open, it takes a lot of work and takes being ready for change.

Having no hope, closing the door on all possibilities other than what you have now doesn't leave room for much change ? It also takes some self accountability and responsability to change, there are plenty of issues most of us dx'd with mental illness that we can work on. Self esteem is usually one of them especially if you are experiencing those kinds of thoughts. Cognitive thought distortions, core beliefs you hold about yourself and the world around you. Lots if good articles right here on pc about this stuff.

Thing is if you dig your heals in nothing will change. You have to rescue yourself.
