All three are blended to "the point of confusion" as you put it. It's the ultimate mystery of faith, one we will never understand even in Heaven. They are three persons, equal as One God.
No, the three hypostases are not blended, they are definitely distinct. So says the Athanasian Creed, and so says the Preface of the Holy Trinity.
They are only "blended" in a very very loose sense reflecting our limited understanding, but they are not actually blended. Equal, but distinct.
