I love someone

I like a boy his name is dylan we are very very great friends but im just afraid to tell him. I think about him alot and i worry about him i know im 12 but i really love him i call him floof because he has soft hair and i pull on it a little he makes me blush alot and hes very funny! He is there for me but he gets sick alot were sick buddies but im sick in a different way... i suffer from serious depression and anxiety but whenever im with him i dont worry about things hes amazing i just dont know how to tell him... :( any advice?
