The horror stories got me terrified of coming out. Instead I still have my home, my house-mate/landlord may not like it but still treats me as a bloke and asks how things are going, my colleagues not only put up with my paranoid days but have been amazingly supportive, and while my Mum still has her moments occasionally, my family on the whole have been brill.
I'm one of the lucky people who've had more positives than negatives when it comes to transition :3
