I'm sorry, how old are you to be saying that?
That's because you're a teenager. You might think everybody else around you are totally okay with talking to the opposite sex, but they're not. Most of them are freaking out and are just afraid to show it.
Probably. I've been single my whole life. Some of us are just doomed to be alone and miserable and unloved forever. Get used to it now so you don't waste your life looking for something that you'll never find.
I'm trying to figure out myself
Because that's life.
