I believe it would be wise for you to speak with a knowledgable minister or spiritual director.
You are sincerely misunderstanding Jesus Dual God - Man nature, and last I heard Protestants don’t believe in Arianism.
You need some help there.

I don't think you have a clue what I get or don't get.
It appears that you fail to see the error that calling Mary *mother of God* can lead to.
Renaming Mary in an attempt to correct doctrine about the nature of Jesus is two things. One - a pretty poor excuse for the action and two - an epic fail at its best.
It makes God and Jesus created beings and elevates Mary above the Godhead.
People who did not have the knowledge to not make mistakes about who Jesus was, are not going to get it right by renaming Mary.
The focus then is totally on the wrong person and the wrong issue.
If the issue is the nature of Christ, it's not going to be fixed by putting the attention on Mary.
