stop being scared find the thing that suits you to tell her and give the thing as well as your love and don't care about her reaction

just tell her how you feel, dont be a creep ab it yknow? just be like, "hey youve been on my mind lately,,, are you willing to go out sometime?" dont be freaked out just be calm and try not to sound too nervous. like shoto said say whichever suits you, but thats just an example you could say,, make it into your own words!! or copy it, idc. good luck :)

if your nervous think of the good things don't go for the bad outcomes. also, you need to be yourself when telling her this because if you aren't yourself then it will be a huge mess. It's ok to be scared or nervous! the thing is if she rejects that love you should know a bunch of people are here to support you and cheer you up in the end.

im idk well go up to her smile(maybe) and tell her i like you then look at her until she respondes

Are you friends with your crush?
