I'm so confused [crush]

Okay so I (17f) am a lesbian I've been since middle school but I still haven't come to terms with it. But I've tried to like i got the heart emojis that are the color of the lesbian flag on a few things I've told like mabey 2 friends im a lesbian I've joined reddit communitys but like deep down im oddly mad at myself. I would say I was bi and that stuck butbsince a few months ago when I kissed my ex guy friend and then in that moment I thought "fuck I'm a lesbian" so I've somewhat was happy myself but also not really since I don't want my family to be mad at me. But anyway my friend that I've known since elementary we got on a call and we were just talking and she asked me if I was gay and if I ever kissed a girl and I told her yea I'm gay but no I never kissed a girl. So I asked her if she was gay and she said no. But ever since then I've just been thinking of her and I've never had a crush on her but like now here I am just thinking about her and wanting to ask her on a date and I'm like wtf is wrong with me I'm like so confused. Has this happened to anyone else?
