I found an article about the possibility of PTSD causing psychosis as well. The reason why I’m sharing it is just so that you know that other things than mood disorders can mimic them. ADHD can do it as well. I recommend if you have these kinds of symptoms to really delve into why you may have them, and have open conversations with your doctor. If PTSD is never addressed, which can happen due to a misdiagnosis of a mood disorder like bipolar disorder, the symptoms of it only worsen. Trust me, as I know this to be true from my experience and others who I have talked to.
