Lost and Confused on the Path

During several years my life has been deeply spiritual. Meditation, reading spiritual literature and a constant inner work and process of spiritual and personal development has radically changed both my inner and outer life. I really felt connected to God and my prayers were literally answered in many ways.

Of some reason which I don’t really understand, now I suddenly feel lost and disconnected. It’s as if a very critical and questioning part of me has entered the stage. For example, reading spiritual books was a thing that really engaged me before, now I’m only thinking “from where do they get this, how can they be so sure of what they saying?” When I pray, I feel like “to what am I praying, what am I doing, why am I doing it?” I feel like I have swallowed a lot of concepts that others have made for me. I want to discover my own truth, but I don’t even know where to start, and also the critical me says there is no truth. I don’t understand at all why I am here on this earth or how anything works, and the more I’m thinking of these things, the more uncertain I get of everything. Where to start and what to do when you feel totally spiritual lost? Since I’m writing this to you, there must be a part of me that believes there is a way back. Now I wonder if you have any advice on how to find that path again?
