crush advice

I'm 13 I will be 14 in 4 months, and I have liked a guy in my year level for around 8-9 months and I really like him, I don't know what to do I'm not sure if I'm friend zoned, I have hanged out with him in a group a couple of times with him, best friend, twin sister and his best friend. I talk to him a lot on snapchat! I really don't know what to do, when ever I'm around him I feel really happy and my heart races so fast, he's so sweet. I don't really think he likes me but we are really close. A lot of my friends are telling me to tell him I like him. But when ever I think of that I get really worried that if I tell him. Things will be awkward and then I Ruin everything! Sometimes I think that I should try to get over him But I really can't. I'm really confused please help. Thanks 💗
