Hmm kay I'll give you my little experience.
I went FT the day I began anti-androgen therapy, mainly because the GD was biting was too hard at that point.

The first couple of months were a big adjustment for me and my colleagues alike.
I also told my parents in a lovely letter at the same time.

Going FT at work and in life benefitted me. Coming to think, it has now been 12 months FT. I'm totally settled and comfortable now, because I've had plenty of time to grow into it.
I've also grown *along with it*, I suppose. Being 'out' and living it while I was transitioning ... has allowed me to freely express what is going on with me and how I feel. That has really helped.

The parents didn't react fantastically well. We did not speak for a year. Mainly because for a long time, they couldn't accept it.
In the past month though, we have reunited. All of a sudden things are fine.
I thought Mum said it well. She said that 'when you weren't around, I couldn't picture it or understand it - but now you are here, it's not as confronting, because it's obviously you'

So I guess that for me ... being out there sooner rather than later made for a sharp learning curve - but now, at 9 months transition, I'm well and truly used to and loving my new life.
Not to mention, that everyone is well familiar with the new me - and have forgotten the old!
