Please someone help me! I am suffering from severe depression after seeing philosophical videos (deepak chopra is one of them) about reality. Many of them talking that reality is an illusion and nothing exists, and used quantum physics as a reference (the observer effect). Others simply say the reality is nothing but illusion and nothing really exists, It's just that our brain creates physical things, and that the space between molecules are "empty", how could something be solid? I'm really lost, I do not know where to go. All of this bothers me a lot - ' Is the 'observer effect' a proof to all of this crazy stuff?
