How are you sure your talking to someone.?

Hello, I am IN LOVE with Sarah Michelle Gellar. I have been for about 8 years. I watch all her movies, all her shows, I'm a member of 17 of her fan sites. My #1 all time dream is to meet her. I doubt she would meet just anyone by me mailing her in again, I don't want her to think im a stalker or anything by writing to her saying..."Hey i want to meet you sometime". I'm only 14. I almost just want to see her on the street and get a actual autograph, and not one I bought on E-bay. I didn't think it would be that hard to atleast talk to her, Because she's not THAT famous. But im not sure im actually talking to HER, And not some Chick that gets paid to read her mail. Does anyone know how I can actually Contact her, or hopefully even meet her? I may sound like an Idiot. But i live near hollywood about 20 miles away. i have mett Jerry Springer and Judge Judy but I can't manage to meet Sarah Michelle Gellar. ='(
