The mood swings, voices and paranoia can all be symptoms of schizo affective disorder.
When I am really sick I have such debilitating paranoia that I close all the shades and stay in the house all the time. I have such anxiety about all the strangers. And even about people I know and love.
I feel the worst when I accuse my close friends and family about something made up in my mind that’s not true. It is hardest on them. They know it is not the real me.
