Hello!
For me, the mental health benefits have been amazing. Every now and then I wonder if I made the right choice. Then I talk with a coworker, who has stated quite bluntly "I like you better as a woman than a man, you're more engaging and pleasant". I have become a tad more emotional, but I find it easier to affect my feelings than before.
Physically, I don't see much in the way of changes, my man boobs are now looking more like real boobs, and occasionally when I look in the mirror, I see a woman staring back at me.
The bad part was my wife decided that she can't stay with Claire, she preferred Steve. She couldn't accept that I am still the same person, just happy. She still is supportive to me, and has even told me to go out and find someone. I felt incredibly guilty when I accepted a young lady's request to take me out on a date.
