Am I bisexual? Am I the only one?

Please help me I am freaking out. All my life I have bre a 100% straight girl. My freshman year I was friends with many bisexuals. And at that time I never considered it! In fact I bashed it! But now, 2 full years later, a completely changed person, and have new non-bisexual friends (cause they were jerks) and now I'm having all these wierd feelings. I'm imagining myself making out with some of my best girl friends??? What's wrong with me?? I feel like my friends and family are kinda homophobic so idk if I could come out.. But also I love guys! I've never kissed a guy but I've definatly liked guys, some for many years! I'm so confused! Is it just a fase? Am I just curious? Or am I actually bisexual? I am soo confused I need help and support please. I feel like Im the only one. Thank u so much! (ps I am religious which scares me even more)
