I was once religious. Back then I almost had n explanation for everything, an answer to most of the big metaphysical questions. Then sth happened that I started to doubt every single thought and belief I used to hold. Now I feel like unbalanced. Every answer could be right. it feels like there's no certain approach of getting exact answer to any of these questions. Some people say that you ought to just get used to this uncertainty, and it'll be a normal state over time. It's been mostly 5 years for me until now and I still feel there could be some kind of truth out there that needs much more research. I am not sure of anything right now but I still have this intuition, and I believe the main aim of most researchers is to grasp this ultimate truth even if it doesn't really exist
