Psychosis is pretty hard to hide I think. Basically any doctor should find out that &quot;there&#x27;s something going on&quot; simply by having a conversation with you. The same is probably true with family (they may notice you&#x27;re &quot;acting weird&#x2F;different&quot; or something like that). If your friends are very spiritual they might think this is normal of course, so maybe stick with professionals&#x2F;family.<p>I&#x27;m not sure about bipolar disorder and similar diseases, but I suspect they&#x27;re much more difficult to diagnose (but also a lot less scary than psychosis).
