You have too many spelling errors to get an accurate translation, but it's something like: "you? happy day desan? itu? you are the best"
Tú eres = You are
what are you?
"I love you. You are the best cousin in the world."

ERES EL MEJOR !! (male) ERES LA MEJOR !! (female)
Spanish > English you are the best girlfriend
"Eres" is the present tense familiar (second person) conjugation of the verb "ser", which is one of the Spanish verbs meaning "to be" in English. "Feliz" means "happy". So the phrase means "you are happy", or as a question "¿Eres feliz?", it would mean "Are you happy?"
Translation: ¿Estas feliz? or ¿Eres feliz?
"Mejor no, eres como loca" is Spanish for "Never mind, you're kind of crazy."
Eres el mejor / Eres el primero
You are the best friend
"Eres el mejor"
Formal: Vd (= Usted) es muy feliz. Informal: Tu eres muy feliz. Also: Eres muy feliz (the pronom may be left out in Spanish).
"You are the best girl in the world" in Spanish is "Eres la mejor chica del mundo."
