Hey Mysterious!
Congratulations! I know how hard coming out to your folks can be. Fortunately, you have the support of your father and his understanding that it isn't just a "phase" you're going through, it's who you are. I came out to my parents four years ago and they have just started to understand the whole "not a choice" issue.
Also, don't give up hope on your mom. My folks were active JWs when I came out, but became inactive about a year or so later (for completely different reasons). After they broke free from the crap the WTS was forcing down their throats, our relationship returned to a somewhat "normal" state. So, there's really no way to know what's going to happen next. Give your mom some time. What you got was her shock. Time will give you her true feelings.
Poz, Way to go! Having the support of your parents makes the whole process, and life in general, much easier!
You both have my best wishes!
Country Guy
