Jesus is the Word incarnated.

Yes. Some Christians tread the Bible as a Holy Book dictated by God Himself. That's Bible idolatry. Muslims do that. We're supposed to avoid it. The Bible was inspired by God (by the Holy Ghost) but it's still written by humans.
Ok, so… the Trinity. First, it's called a mystery for a reason: don't expect to ever fully comprehend it. That doesn't mean "don't try it", just that there's always more.
Imagine we have God, at the beginning of time. Well, actually, before time. And there He is, all omniscient. When limited being like us try to know something, we create a copy of it in our mind: an imperfect copy, an abstraction.
God, when He understands something, creates a perfect copy of it, cause He can understand things fully. When God understands Himself he creates the "concept" of God, fully realized, with all it's characteristics. And that includes existence. That "concept" is the Logos,in Greek, the Word. Not the spoken word, but more like the underlying concept too. It's interesting to point out "Logos" can also mean order.
So, we have God and the Word. We call them God the Father and the Son. Both are fully God, but at the same time are different. And in the same way the Word is created when God knows Himself, once he has that concept he loves it. And from that love we get the Holy Ghost. The Son comes from His intellect, the Ghost from His love.
Now, to love a concept you first need that concept (duh). That's where the "fililoque" comes from: the Spirit necessitates the existence of the Son. Those who reject the "fililoque" point out it's the Father doing the loving. As far as I know, both positions have fair points and it comes down to the exact meaning of word in Greek and Latin (the Catholic version of the Creed in Greek has no "fililoque").
Now, something important: God cannot no know Himself, nor not love Himself. The Father doesn't create the Son and the Spirit through His will. That's why they are not created, why they are "begotten, not made, consubstantial with the Father".
Hopefully, if I wasn't too unclear, you can begin to see why Jesus is God. He is the Word incarnated. The Logos in flesh. The "concept" of God in human form. If He was God the Father, that'd be impossible, and that's probably why the concept of "Jesus = God" is problematic to you. But He's the Son, and as we saw, He's fully God too.
This appears at the beginning of the Gospel of John (John 1:1-18). It's a short paragraph but a densely packed one. I recommend you read it carefully, with a good Bible with annotations. It'll help you understand it a bit better (to the extent this all is understandable).
I hope I was able to help you, OP.
