Amoré-
Please don't harm yourself - what you are going through - although it is heart wrenching and awful - is survivable. There is a better life on the other side I promise.
Where you are now is smack in the middle, and thats the worst place to be. I can tell from what you wrote that you are vacillating back and forth between living as the old you and living as the authentic you - thats the authentic you fighting to emerge and live.
It sounds very much as if you are a transsexual - if so, the gender dysphoria will only get worse and worse. Many of us have been down this same road, holding on to a life thats not real, trying to be a certain someone to somebody. Some of us can live that way but most can't - I think judging from what you have said that if you continue to "hold the line" it will eventually wipe you out.
Your wife does not and cannot understand this - she doesn't have the condition and it seems foreign and strange to her. This is a condition that you were born with - you did not choose this - it is a birth defect, a medical condition that requires treatment. Like any other medical condition that is left untreated it will only get worse. The treatment for this condition is to realign the body with the brain.
I feel your pain of trying to hold it all together - I was married for 27 years to my soulmate, but my ex could not deal with the authentic me and in spite of me trying to hold it all together she split. Your wife knows about the authentic you and try as you might that genie is not going back into the bottle. She knows enough about the authentic you that her perception of you is different than it was before and it will continue to be different. She is reacting to her own pain by lashing out at you.
You have an advantage of already looking like any average girl on the street right now with the short amount of time that you have been on HRT. That will only help your transition.
Don't throw away your stuff - if necessary put it away. Getting rid of your stuff won't fix how you are feeling. This is very a common thing within the community and most regret doing it later.
What you are going through is scary and is full of unknowns. As you said - you haven't yet gotten to a point of accepting the girl in the mirror. She is the authentic you. Please work with your therapist to find the way forward, and try not to fear what lies ahead for you. Yes, it will be hard and challenging, but you can and will get through this.
Speaking as someone that has made a large part of the journey - living an authentic life and shedding the old life's baggage is simply wonderful and IMO it's worth the price of admission. It won't fix all of the problems in your life but it will fix the big one and will allow you to move forward in life.
As far as friends and family go - some people will make the journey with you and some will choose not to - you can't control that. You will find that being an authentic you will draw new friends to you - it did for me.
