I learned for me anyway that any visual or sound you interpret is real it is just being tampered with through your senses. That made the derealization and everything i was misinterpreting as all of it being real. I learned that my wrists are as skinny as I think they are. Some days they might seem skinnier than normal. What psychosis does is it plays tricks on you. It will make the seemingly out of place so out of place that you begin to question whether it should fit there in the first place.
I didn’t want to post if I couldnt be of any help to people experiencing psychosis And I think that it helps to journal symptoms so you have it on record.
