I know only one PS on a personal basis that is...my nephew (I'll call him Ray). He appeared to be a normal up until the age of 22 ( which drs. did tell us this was an age where symptoms begin to immerge ). Suddenly Ray is accusing us all of drugging him and taking him to the local college to have a micro-chip implanted under his skin. I could go on and on about his off the wall behavior. Ray was so distraught about the micro-chip incident:frown: he called several family members telling them he was going to kill all of us who shared his last name.Ray thinks everyone is following him,spying on him,he hears voices that ask him to do things,he's delusional. He has cut his wrists before, but said someone else did it(nearly bled to death). I'm getting off topic here,but this is my personal experience with a PS.
BTW... working in surgery over the years , you would be amazed at how many mentally sick people suffer before seeking medical help. A guy who got his scalp lacerated with a bottle,bandaged it himself with a cast made of flour,water, and paper towels...9 days later he is brought into the ER by LE.
