I'm 17. I think my previous crush is playing mind tricks on me.

Hi , about 4 months ago I had a crush on a girl. During that time my studies weren't that tough, I just enjoyed being in class. One day my friend told her that I like her. We chatted for a while but I realised that she doesn't likes me. So we both blocked each other.

Now, only few months are left for the final exams. Stakes are high. Now she along with her guy friends started roaming around me.

But today when I was in boys washroom, her male friends started asking me wheter I like someone or not. I said that I'm too busy in studies. I also observed that she started panicking out when I was asking question to my friend and she was standing right behind me

I just want to say I STILL like her, buttt I need to study otherwise I will be f#cked up. I think I should keep her as casual as possible to focus on studies
