Glad things are on a good footing with your wife, she is a saint to walk this through with you. I agree fully with Laura and Reine that your therapist was way off base to diagnose you so quickly and recommend HRT so soon. You need to go through a significant testing phase to determine what she did in a 1 hour appointment. Doesn't sound like you agree either or that is where you are in like. Pink Fog is best descriptor for you right now. Be easy on your wife, go easy and slow, you nee each other. Let her experience the man she married as much as possible!
