Thank you for all the replies.
I am definitely going to seek a second opinion as soon as I can. If all else fails, I will blow some vacation time and head to see specialists in Chicago.
Quotelive for the rest of my life extremely depressed, trapped in an alien body
That is definitely what it's felt like for a long time for me
QuoteI would still bind, change my name, explain my pronouns to people, try to learn all the little habits that cue my gender to others, etc
I do bind, although it doesn't do me much good - even after getting down to 17% BF, they're still horrible and huge

The name is at least easy for me - my parents gave me a typically male name at birth (and actually asked if that was to blame when I first brought up wanting to be a guy to them years ago). Short hair, no shaving, boys' clothes, bound as tightly as I can, and I still get "miss" everywhere I go. I do need to work on gaining the confidence to tell them not to do that, though. Usually I just take it in silence.
QuoteDid he say your condition?
I'm fairly certain he did, but I didn't catch it as I was too busy flipping out. My GP just refers to it as "estrogen dominance syndrome," and my google-fu has been failing me on that one for the past two hours - apparently, it's not a specific diagnosis. I will have to contact the endo's office on Monday to actually get the figures and have any documentation sent to me before I start shopping around for that second opinion (or third, or fourth...)
QuoteAs for top surgery, there are surgeons that will perform that operation without ever being on hormones. Most of them would require some type of letter of recommendation though.
Thanks very much for that - I will check around and see about getting recommendations from my therapist and/or GP. I'm pretty sold on the idea of this - I've really and truly hated them for such a long time.
Thanks to everyone for responding - and I'm really sorry that I only joined and posted when I had such crappy news. I will try to get into some happier threads this weekend, and contact the endo and several others on Monday. And bring up all this with my therapist during my weekly on Wednesday. For now, I'm off to try and slam as much of my freaking out as I can into my heavy bag before crawling into bed.
Seriously, thank you all so much. I probably would have spent weeks feeling totally lost and beaten down before coming to the conclusion that I should see another doctor on my own.
