socializing dilemma of a new socialite

Greetings! I have something to get off my chest and I hope my mumblings won't bother anyone here even though this site might not be the proper place for me to share.
It's all about the socializing issues I'm having right now, and it is very hard for me to keep these issues to myself because I don't think I can share with anyone else in real life.
Here we go: I've been heavily involved with the new york high society recently after I made my debut not long ago. A brand new world to me and I think I'm doing fine and it looks like where I belong.
Now comes the problem: as some wise people would describe me: I'm a very private person. why am I so private? I don't know maybe because I just can't trust people. I remember I've seen someone saying here that"only the paranoid survives", I couldn't agree more. I've been very careful with my real online image: I've been meticulously controlling the number of people on my friend list of FB, I don't use LinkedIn or so. I googled my name and my email address once a while just to see if something about me comes up. After I see none, there's a big relief.
Why I'm like this all comes down to my plan: I've been developing a plan to hit the headlines soon in the future (with positive news of course) and I'm worried that the media will all come to dig my past all of a sudden. I won't like it at all. but I need to be hitting the headlines. That's always my goal.
So I'm in this high society circle and it is relatively small. People know people. I've been getting to know new people constantly and they hope to get in touch with me. Some asked for my FB info or so. I'm mind battling now if I should add those on my friend list which is composed of my school friends mostly whom I believe won't sell me to the media someday. But these socialites, I lack such faith in them. I think they all want attention and fame.
So any ideas about how I should respond to their friend requests? On social media particularly? thanks
