Hi there,
I think we are in similar boats. I considered doing the "pre" weight loss but ultimately I think that what is killing me is a two-fold weight and dysphoric feeling. So, I am having gastric bypass approximately 2 months after I start hormones. I am starting hormones Sept. 24 because that was the earliest appointment I could get.
The waiting is hard. Hell, let me be real. My HRT letter was approved Monday. I was elated. Then, I didn't know what to do. The past few days I have spent cycling between "I won't pass/be pretty" and "Am I making a huge mistake" and "why can't I just start now!" Things I've read have indicated that all of these are normal, considering my sitch.
I've also read that having a hobby is a good distractor. Not for me. My hobby is obsessing about passing. Worrying about it. Wondering if I'll be a freak. Laughed at. Then I get depressed about how this is changing my marriage, wondering how people will react...
So....I don't think that's much help, but you aren't alone.
