welcome to beyond blue.
I don't know of any specific place where you can discuss "psychotic symptoms". If you do a google search on
beyond blue psychotic
on the first page of the results you will see a number of different threads in different sections of the forum such as anxiety, depression, young people, etc. so rather than point to some particular page, think a search would be better for you? With that said, you could use this as the start of a new topic about this. So what you could do is look at some of other threads and post there, and you could direct them here also.
