Boy troubles 😬😂

So basically I haven’t shared this with any of my friends because I feel like they will judge me. I have a crush on this guy who is two years younger than me. However I’m still in school and so is he and I don’t know what to do. I know it will be ok in the future but what do I do? I just need some advice because I haven’t told anyone. People in my year have dated people two years younger but it’s mainly been boys not a girl dating someone younger. I have finally realised you can’t help with who you fall in love with. I literally like him so much. I don’t know what to do.
