I want suggestion

I had feeling for the girl. My best friend introduced once and from that day i had a big crush or attraction towards her. Its about 1 and a half year since we became friends and *** she friendzoned me by saying mee a best friend and sending that type of reels in my dms. Sometimes i think ishould made a confession but i don't have the courage to to say and my biggest fear is that if she would say i done all those things in respect to a good frnd then i'll be completly broken from inside.

So please help me by giving suggession what to do about it should i make a confess or should i wait more to devolp feeling against me inside her.....
