There are hundreds. For the "too much", we even have evidence from brain damage where the emotional response has een lost - these poor people can't decide anything of any complexity - they just dither back and forth.
For the more direct, think of deciding whether you like someone or trust them or love them. Those are emotional decisions.
Though it won't stop the pain when it becomes real. The future is not real and we all need to understand that, the things we do now are only in time with now. The future is an instant that has yet to be revealed.
Faith trumps nothing. Faith can't move mountains, can't change cause and affect, can't do anything except comfort those who need it. Comfort isn't a bad thing at all, so I'm not against faith, but that's all it is good for.
I think that controlling our now is an illusion. The illusion is fed by the world around us. To ride a wave, you don't control the wave. You become one with it. Control, if we have it at all, is momentary.
