I was wondering why the pronoun te is needed in these sentences:
No te preocupes. (meaning "don't worry")
My confusion here comes from the fact that preocupar is already conjugated to tú form. Why is it "don't you you worry?"
¡Que te sientas mejor! (meaning "feel better")
My confusion here comes from the same thing as above- why the repeat of "you" pronouns?
