Do you think hospitalisation without someone's consent is a good thing?

I've always been given a choice which is I think pretty useless (at least in my case). But I'm not sure it's a good thing at all even though I regret my choices (but not much: I believe in fate/inevitability, God's wisdom and even though it might have been good for me, I don't think correcting people is good for society and in the end isn't good for anyone, not good for the spirit, so to speak).

And can you make better or truly your own decisions when medicated?

I think you can, but the wiser choice is to do the things you wanted when unmedicated (in essence), with a better chance of succeeding. To not try and rectify all of your (psychotic) beliefs.

You can't be very good at being what you're not. Separate yourself from your madness completely. You should use what makes you special.

Do you agree and in what way do you try to do that?

I try to balance the irrational with the highly rational, to minimise rational mistakes, to be extremely rigorous in analysing my beliefs. Psychosis is the best way to test that and practice that, reintegrating delusions into your more usual reality, and preparing for that is the best way to deal with psychosis.
