I am one year post SRS, have been on HRT for two years.
The changes keep surprising me.
My impression is that <his name> and <her name> share this body, but she is at the wheel now big time, making the rules.
His personality is sad, lonely, downcast, resigned, cynical, determined, no-nonsense badass. Don't mess with him.
Her personality is optimistic, friendly, sociable, outgoing, tendrils and flowers. It appeared with HRT, unasked for, but greeted with tears of unspeakable happiness.
You WILL BE SURPRISED. Nothing and nobody can prepare you.
