Sending you encouragement! I am sorry to hear that you've hit a rough spot...but know that it happens to all of us from time to time...and that it is a temporary detour in your recovery journey.
I do hope you can find another doctor that you can come to trust, like your current doc. Maybe he can make a recommendation for you?
Remember that for every new challenge...a new coping skill can help...and bring about
"Courage is not the abscence of fear, it is feeling afraid and doing it anyway!"
"Worrying does not empty tomorrow of its troubles...it empties today of its strength."
