So, I am a teenager and I'm older than sixteen years old. That's all I'm going to say about what I am. The thing is that all of my friends have had dates and have had boyfriends and girlfriends and I'm feeling... left out. I'm that person that everyone becomes friends with but doesn't like more than a friend. I'm also that single friend who gives great couple's advice, but that isn't the point. My question is should I even be jealous? A friend of mine told me to wait until college to start dating, but she's been with her high school sweetheart since she was a freshmen and she's a senior this year. 

Should I wait? Or am I doing something wrong?
