Hello emmamental: I don't know anything about your situation. But since you mention your diagnoses, I presume you're seeing a psychiatrist and / or a therapist.

The experiences you describe sound to me like the symptoms one would expect in a person who struggles with schizophrenia & obsessive thinking. So my suggestion is to talk with the mental health professionals in your life about what you're experiencing. If you're not seeing anyone currently, please do so.

It is certainly possible, even probable, there are other members here on PC who have similar experiences. However, knowing that will not make any difference in your life. In order to heal you need professional mental health services. I wish you well...
