No matter what your age is, it's always hard to try to get over someone you like. But the most effective way is to keep yourself busy and try not to interact with him in order to keep him out of your mind. When you're busy doing something else, your mind is focused on what you're busy with and it won't drift to thinking about him. When you don't see him anymore, then you're also less likely to think of him. It will take time however almost everyone goes through this at some point in their lives so I know that you can too!
im in seventh grade and i have a crush on this guy named brock. hes really cute and sweet but im pretty sure he doesnt like me back. how do i get over him?
You realize that crushes are mostly one sided. They disappear as quickly as they appear. You're very young .. And not ready for a boyfriend anyway. Try to be realistic and remember you can't lose something you never had. You say you're in 7th grade. Are you only 12?
