I know a woman who was psychotic due to a genetic disorder. DiGeorge syndrome. It can cause major MIs such as Bipolar and Schizophrenia. This is a rare disorder so certainly not main cause of most MIs. Back in 2014 she sufered delusions concerning her and relationship to a certain actor. Believe me there was no such relationship. She became very verbally abusive toward me including threats of physical harm. Then sometime in 2015 she suddenly because friendly with me. No explanation, nothing. It was like verbally violent with psychotic thoughts than next day back to normal. There was no apology and no explanation. Never asked for an apology or explantion. I let her behavior slide. I am friend with her but I'm playing it be ear. Do you think I'm doing the right thing?
