confession

So I've had a crush on this one guy for atleast more than 2 years now. His my mom and my mom are best friends. My friends told me that I have to confess to him before anyone else does, but I'm super nervous! This is my first time confessing to my crush! I've never told any of my past crushes my feelings for them! I've never faced rejection before! Please give me your best advice, I need help!!!!
