I didn't read most of this, but I wanted to comment on what I read near the beginning of the thread.
I came out to my wife when she was about 4 months pregnant. She immediately got on a low-ish dose of Zoloft and it helped tremendously. She was coming unraveled pretty quickly in those first couple weeks and it did wonders.
During the next 5 month I explored my femininity with a vivacious abandon. Clothing, makeup, shaving, making new friends, therapy, hormones, laser hair removal, the whole 9 yards except for voice training and planning for surgery! I'm not out at work, but I am to many of my friends and family now.
Here's the kicker. Our daughter was just born on 9/10/15, so she's only 6 days old now!

During the last week, I all but switched back to boy mode. No earrings, no makeup, no nice clothes. Just a shower, hair styling, jeans, t-shirt and sneakers. I fell into the role of a parent. I wore what was comfortable, didn't go to work (I'm back today), and I did what needed to be done. I wasn't expecting that to happen after so many months of obsessing about being trans, but I did. Becoming a parent flips some switch in your brain that makes you Take Care of Business! Suddenly your child is the most important thing in your life. I kept taking my meds, but today is the first day I've worn my women's dress pants and panties since the birth.

Basically what I'm saying is that some of the fears should be alleviated. Just because you want to change your physical appearance, social standing, clothes, gender markers, or whatever, doesn't mean you're not the same person. If you want to be, you will still be a good parent, regardless of what medications you're taking or what's in your wardrobe. Tell your therapist that there's no time like the present to be yourself. Stop suppressing it and you'll be happier, and you'll be an even BETTER parent for it.
