Lori,
Your wife is lashing out, its the normal first phase.
This is a bit like a 12 steps program for her, acceptance doesn''t come first.
She's got to mourn who you were before she accepts who you are and will become.
It took you years to come to this point, it won't happen overnight for her.
As for changes, your just starting HRT, the first few months, the facial changes are seemingly imperceptible until they pass a threshold where cummulatively they have an impact. Look at my picts, or Kate's pics, our before pics were more male than yours but, 10 months later I can't even pass as male in the most drab clothes possible without makeup.
