I'm not sure what to do. Am I a stalker?

[Cameron]

So, when I first got to high school, I was amazed by all the things I saw, but one girl with a short pixie or "dike" haircut always caught my eye. I thought I'd just forget about her. After about a week or two, she still was on my mind. I had seen her before but I'd never really paid her much attention.I'm not really attracted to anyone. I've met two girls in the past four years that i'd even consider being in a relationship with.(I'm not gay lol) I could tell she was the same artsy person that I was. I'm not generally a shy person but, when ever I even catch a glimpse of her, I feel like crawling into a little ball. I've made numerous attempts to talk to her but I can never even get close. The weird part is that, I've started watching her from a distance. She doesn't seem to have a lot of friends, but a circle of about 6 or 7 people she usually hangs out with. I asked one of my friends who had went to school with her. She was a grade above us, so she didn't know her name. I had to ask around to find out who she was. When I found out her name, I looked her up on Facebook. She had many intelligent post. I knew she was smart. We watched her class get awarded academic achievements. At that ceremony, she got 6 awards. Also, saw her in a dress for the first time. I knew i had to have her. She dresses differently too. I was voted best dressed 3 years in a row if that says anything. I really want to talk to her but I just cant. Once, a group of my friends even tried to help me speak to her. She seemed bothered by us so I didn't say anything and stood there awkwardly as she rushed to art class. One of my friends that went to school with her, said that she was kind of a bitch. I've also heard rumors that she's a lesbian. I could somewhat see that as a possibility. I'm not sure what to do about this. Every time I log onto Facebook, her page is the first that I go to. Just a few minutes ago, I liked a recent picture that she had posted. I'd never done this before. I refreshed the page and her icon didn't show up. My heart dropped at the thought that she deleted or even blocked me. I went to the home scree and tried again. She had just logged off. She posted a few things about Christmas.
Please help! I sound and feel pathetic as I type this. I feel like a stalker and I don't know what to do!

Quit stalking.

TALK TO HER!!!! Find out what she likes by stalking her (like you already have been doing) and go up to her in between classes and flirt!

Kind of. She doesn't even talk to you and you "liked" her picture lol that just radiates weirdness. I don't see the point in being into her since she is most likely a lesbian and I am pretty sure you're a guy. It's just wasting your time.
