Surprisingly, I have been supported by literally every single person that I know.
The second I realized that I was a transgender woman, I came out to everybody (this was months before I even attempted to present as female, let alone starting HRT or anything). My boss at work asked me to just please let her know when/if I'd like her to start using a different name and pronouns, and no one there has made a mistake once since I did. The first time I came into work presenting, she complimented me and said that I look just like a girl. I also managed to get hired at a second job somewhere else as an out trans woman. No one there has ever made a mistake in regards to pronouns either ... And just to be clear, I do not pass as female. People who do not know I'm trans (customers, etc.) refer to me as male 99% of the time, even when I'm wearing full makeup and a dress showing off my bra ...
Anyway ... My daughter's mother (we were already separated before) has been doing everything she can to get our daughter to stop calling me "Dada" and instead refer to me by my new name, etc. Our daughter is only four, so it's been a slow process, but she uses correct pronouns now about 50% of the time.
I have gotten into three different romantic relationships as an out trans woman. The first was with a woman who I went to high school with (so who knew me from before), the second was with a polyamorous MF couple, and the most recent is with a wonderful young lady. The first two ended for unrelated reasons (essentially incompatibility), but I have been in the relationship I'm in now for 5 months and it is absolutely lovely. She still lives with her family and even all of them refer to me with correct pronouns, etc.
My family, my friends ... It's all the same story.

I hope this post doesn't come off as bragging, I just want people to know that it
can go well!
