Hi John,
John 5:37 And the Father Himself, who sent Me, has testified of Me...
So what Jesus said is true; a being, the Father sent Him. You don't send yourself, the Father (one being) sent (another being) Jesus Christ. Also Jesus prayed to the Father, not Himself. Jesus spoke of His Father often, He was not speaking about Himself.
John 12:49 For I have not spoken on My own authority; but the Father who sent Me gave Me a command, what I should say and what I should speak.
But no doubt most get confused when Christ said "believe Me that I am in the Father and the Father in Me" (John 14:11), this does not mean they are one being. This is the indwelling of the Holy Spirit that made them ONE, just like we too have the Holy Spirit indwelling that gives us oneness with Christ and the Father.
John 14:23 Jesus answered and said to him, "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him.
This is a complicated topic, just keep reading and studying and slowly but surely things will start falling into place like the pieces of a puzzle.
Something that really confuses me is if no man has seen or heard the Father, then who was speaking at the baptism of Jesus?
John 5:37 ...You have neither heard His voice at any time, nor seen His form.
Luke 3:22 And the Holy Spirit descended in bodily form like a dove upon Him, and a voice came from heaven which said, "You are My beloved Son; in You I am well pleased."

Notice that it was "a" voice, not the Father's voice. God has many millions of messengers (erroneously called "angels" in Scripture). A messenger delivers messages. These particular message was that "This is My beloved Son, in Whom I am well pleased, hear ye Him." The messenger ("a voice") delivered the message. Simple, huh?
God be with you,
