You might be a lesbian. But then again, you might not be. Don't worry about it. It matters not one jot. The person you ultimately fall in love with is not a conscience decision you make. Girl or boy, it's not really your choice. Go with it however it leads you.
You're probably going through a 'crush'. People talk about 'crushes' in a sometimes condescending manner. They shouldn't. I had crushes at your age and I know just how real they are. They hurt.
However, the bad news is that there's no quick fix. Nothing I (or anyone else can say) will make you feel better. You've just got to just ride it out. Painful as it may be, you'll emerge at at the other end a better person and more emotionally mature.

No one's laughing at you. Good luck.
