Schizophrenia Symptoms and Signs

Paranoia is another very common sign of schizophrenia. A person may constantly believe that someone is watching, spying, or planning to harm them, even if there is no evidence. This fear can stay with them day and night, making it impossible to relax or feel safe. Even when they try to convince themselves that everything is fine, the anxiety often remains. Over time, this constant stress can cause exhaustion, sleeplessness, and a growing sense of insecurity.
