Hugs to You Terra,
I went through a situation similar to yours. It didn't matter that I'd come out to my parent's (and my siblings, when my parents exposed my transsexualism to them, during a particularly nasty blow-up, shortly before I turned 16) when I was a teenager in the late 70s, things were still pretty bad, when I started transitioning at age 35 (I tried transitioning earlier, in my 20s but there was nada for transition resources at the time) - the only the only thing different, was that my parents didn't yell at me like they did when I was a teenager. My family said they could accept me being gay, but not being their daughter or sister. Oh yeah, and mom said "don't complain if things get bad for you, you made your choice to live this way!" Friends said they didn't see how I could think I was a woman, since I "did so many guy things (rode motorcycles, played electric guitar, fished, etc.)." Friends left, and family ignored things by treating me like I was their weird son or brother (the extended family [who may or may not have been told about me by other family members] was never contacted by me).
It was always hoped by mom & dad, that I would "come to my senses." My brother and sister just plain decided that they didn't want anything to do with me (to this day they prefer to limit any contact with me). In 2000, I got fed up with my family's attitude towards me, and basically became estranged from them, having very little contact with my parents beyond the very rare tension filled phone call from mom, until shortly before my SRS in late 2003. 2000 to late 2003 was not a fun time. Due to corporate downsizing, and a recession being in progress (which made finding another job almost impossible for me), I was forced to take a huge cut in pay in 2002, that made SRS look like an impossibility (for a while in 2002, I became suicidal because of my financial situation, and SRS looking like a "no go"). I remember spending Xmas 2002 with a post-op friend of mine and her family, and crying my heart out because I was unwelcome to spend the holidays with my own family.
Hard as it was, I did manage to ride things out. The situation became better, and I was able to pull off having SRS in late 2003. In Oct. 2003, my mom made one of her rare phone calls to me, asking how things were going. I told her I was having SRS the following month in Thailand of all places!! It ended up being a very short and unpleasant phone call. Less than a day later, mom called back, and dad also talked to me (for the first time in 3 years)! Neither of them tried to dissuade me from having SRS (I think the fact that after 25 years of knowing about my transsexualism [combined with me being serious enough to have SRS] they'd finally come to grips, with it being the real thing - not "just a phase I was going through"), but they did try to talk me out of going to Thailand (they offered to pay for me having SRS in the US). I told them "sorry, but no can do", due to me having already put down a $1500 deposit for my surgery. So, instead, my parents asked if they could help out in other ways while I was laid up recovering from my surgery. I accepted, and as a result, they took care of my apartment, and helped financially with paying my bills (I had to take a 2 plus month unpaid leave of absence from work for my SRS, and recovery time for it). Figuratively speaking they were a lifesaver!!
Now the moral of my story - as hard and rough as things were, there was a light at the end of the tunnel. Due to reconciliation with my parents (which started with that phone call from my mom in Oct. 2003), I grew to have a close relationship with both of my parents. I did things with them (including spending holidays with them). Both of them openly expressed that I was their daughter, and had no issues with being seen in public with me (I think the first time we went out to eat together in early 2004, and seeing a waitress at the restaurant ask "what'll you have miss?", pretty much put the final nail in the coffin for the idea of me being not being their daughter). I just finished talking to mom on the phone (confirming that yes, tomorrow [Mother's Day] I'm bringing my smallest acoustic guitar along with me to play music, and I also will bring my notebook computer, so we can record her recounting of her life's story for future generations of the family [Mr. IT, my brother, seems to have no interest in doing so, so as I've done numerous times for other things, I've offered to assist mom with this endeavor]). Dad is gone and I miss him (he died 4 years ago of cancer [I took care of him a couple of days before he died, so mom could run some important errands]).
Please don't completely give up hope with your family Terra (although, by the same token, don't knuckle under to them - be true to yourself). It may look like an impossibility, but things may work out for you family-wise (they did for me, when it looked like all was lost in that regard).
