Any good anime out there or manga?

Hey there I am a very bored person right now because I can't find any good animes or mangas to read, I am currently reading and watching naruto, hitman reborn, vampire knight, tegami bachi, zombie loan, ao no exorcist, shugo chara, death note, full metal alchemist, blood+, kaichou wa maid sama, special a, gosick, deadman wonderland, beezlebub, and tons of other ones. I like action, horror, supernatural, maybe some fantasy and maybe some sports since I am in love with prince of tennis. Help please? AND can you please give me tons and tons of suggestions? THANK YOU TO ALL!!!!
