I'm in love with my bff but I've never liked girls before...

I’m in love with my best friend and nothing makes sense anymore. But I seem to still be really into guys so I’m not all vagitarian. But this secret is making me so miserable. It got a little better when I told her, but I’m still hiding from so many people I love and it’s tearing me apart.
I like to tell myself that this all started at the beginning of the semester when we moved in together. I like to blame this on all the flirting and coupley things we did and the constant outside confirmation that we look like we should be together. But the truth is I think I knew the moment I met her.
It was the first week of college and I hadn’t really made any friends besides my weirdo roommate. I was sitting in my room all by myself, listening to the excited chatter that was coming from the hallway. My roommate was out there so I figured I should make an effort and join the conversation. I went out into the hallway and walked up to the group. And there she was. She was the first person I noticed and all I wanted to do was talk to her and get to know her. And so I did. We talked a lot that night and then the following nights and eventually we were just inseparable.
The more she told me, the more I loved her. She was damaged like I was, I liked the scars on her wrists even though they made me sad at the same time. And I never told her any of this, but I knew I would do anything for her.
But she doesn’t feel the same way and it sucks so so much. I just don’t know how to move on or go from here. Do I try and move on by just dating tons of guys like I used to? Or does this mean now that I should try to move on with girls?
Please someone help. So far nothing else has.
