Did the robot voice happen when you were in bed either asleep or half-asleep, or did it happen when you were out of bed and awake?

It doesn't sound like your mother is particularly understanding about this, and people throwing wild accusations at us only makes the stress worse. I'm sorry you're going through this.

It is important that you tell your therapist that you feel like you can't take this anymore. It's important enough to call him/her and leave a message on their voicemail.
