I think you should definitely let your pdoc know about it, even though it's not THAT recent. It may affect how your pdoc treats you now because he/she can look back at what you were taking and dosages at that time.
I like the idea of having your boyfriend go with you to an appointment. If you were psychotic at the time, I'm guessing there may have been warning signs your boyfriend might have been able to notice if he had been educated and aware of what to notice.
Do you know what time of day the messages were sent? I wonder if they might have been sleepwalking? Just a thought.
I'm so sorry you're going through this. You will get through it and everything will be okay. Things have a way of working out.
