Facebook....the biggest leap

So I changed my name on my facebook today and I'm really scared. I have removed some family and people I dont really talk to. But I worry about having my parents on my facebook since I haven't told them yet offically anyways. I casually mentioned it to my mother and she didn't seem too thrilled with it, but I can't keep going on trying to live a double life. I get that work isn't going to be changed until I get it legal but my friends and family need to know. Its hard enough for people who know, to address me in front of people who dont.
