What do I do?

I am exactly like you! I am also a very shy person but I'm gonna share with あなた the tricks and knacks I've learned on how to just get over it.

First of all, あなた know that he knows but the worst thing あなた can do is to just stop talking to him. あなた say あなた wanna talk to him, so, as much as あなた don't want to see this, just talk to him. Not about the fact that あなた like him but just about ランダム stuff. Be yourself, get to know what he likes and see if あなた two have things in common.

The best way あなた can start によって talking to him is to casually say hi at school and if he's in any of your classes just ask an how are you? And あなた don't have to say anymore than that. That way あなた seem open and friendly. If your too shy to say hi, try to smile. A casual smile. Guys go for girls who seem friendly no matter what あなた look like (although I bet your very beautiful duh). The fact is because your 芝居 kinda cold, it sends a wrong vibe to him. あなた shouldn't be ashamed that he knows. It might actually be flattering to him ;)

あなた need confidence too. A great way to get started with that is によって making sure あなた have great フレンズ who support あなた and make あなた laugh and feel good. Hold your chin up, even if he don't like あなた now, doesn't mean he won't in the futur. Ask your フレンズ to accompany あなた to ask him to chill with a group, great way to get to know someone! Your with your フレンズ so あなた feel confident, and it makes things less awkward. Just as long as あなた start によって being フレンズ and don't get your hopes too too up cuz there are a lot of 魚 in the sea and your still a freshman so girl, あなた got plenty of time!
