It may be the best thing that has happened for you, Wildflower. Your husband may appreciate the benefits in your improved feeling tone once you've been stabilized.

His anger is uncalled for, however, in my view. Is it a threat to his ego?
One would think that he might have compassion for his wife's distress.
Ask him what's happening to his compassion for you.

You're not a loser. Dismiss that idea from your head. You are stronger than many who won't accept that they need help and won't see a psychiatrist, period. That might be considered being a loser, in my view. Your self-image might need a little "attitude adjustment"; you're far more valuable as a human being than you give yourself credit for being. Try to remember that.

Please try not to worry; your psychiatrist has really valid reasons for wanting to double check your chemistry and make things better for you.
Any worry just creates more stress for you and that affects the
acidity of your system. We need to keep it calm always, if possible.

(Enjoy the peace while you're away from home for a few days!)
