Help?

I’m 16 and Bi, I’ve known since 5th grade that I like both genders and I had a girlfriend in middle school. But since I got into high school it’s been really hard to put myself out there and search for a girl to make a connection with and date ya know?

I always thought girls just don’t know I like girls but it’s like, what am I supposed to do? Yell “I like girls!” in the Hall????

This seems like a dumb problem but I could use some advice 🤷🏽‍♀️
