> Jesus is a human embodiment of God (according to the Council of Nicaea) so he is both himself and his Son.

What you've described is called "modalism" (aka "Sabellianism", after a guy named Sabellius) and is taught against in Scripture and rejected by the Church under all non-cultish denominational flags. The doctrine of the Trinity is difficult to "wrap your arms around" but very easy to state:

1. The Father is God.

2. The Son is God.

3. The Holy Spirit is God.

4. The Father is not the Son.

5. The Son is not the Holy Spirit.

6. The Holy Spirit is not the Father.

7. There is one God.

From this the language of the Trinity (1 being, God, who consists of 3 persons, the Father, Son, and Spirit) was developed by the Church to describe what is taught in Scripture.
