Hey Davina, I ended up in the same place you were, realizing that however bad transition might be, it really couldn't make things any worse than not transitioning. For me, it was the depression that did it. Getting to the point where I started to think that everyone would be better off without me. I've gone down that road before, but I've got kids now, and it scared me to think of where I was heading. More than transition scared me.
I know there's gonna be some challenges along the way, but I'm a week into HRT now, and it hasn't been nearly as bad as I thought. I've come out to people who are supportive of my decision, and God what relief it is not to have to hide this from them. It's like my life has been on hold all these years and I can finally start living.
As for HRT, already it's a huge improvement. I don't smell like a guy anymore! I never imagined how big of a difference that would make. Overall, I just feel a lot more comfortable in my body.
I'm so happy for you that you've decided to re-start your transition. Let us know how it goes!
