You fear what it would mean if Jesus really is who he claimed to be—the eternal Son, one in being with the Father
When he claimed one with the father he also asked for his followers to be one with each other and with him and his father.
[20 I make request, not concerning these only, but also concerning those putting faith in me through their word, 21 so that they may all be one, just as you, Father, are in union with me and I am in union with you, that they also may be in union with us, so that the world may believe that you sent me. 22 I have given them the glory that you have given me, in order that they may be one just as we are one. 23 I in union with them and you in union with me, in order that they may be perfected into one, so that the world may know that you sent me and that you loved them just as you loved me.]
I follow the Lamb who is on the same throne as the One seated on it (Rev 22:1).
You are using the wrong verse there to show that both God and the Lamb are on the same throne. At that point they are each on their own separate thrones. When Jesus was resurrected and ascended to heaven is when he sat on his father's throne with him. (At his right hand.) That's where he is still today but he knows he will have his own in the future when he comes, so he was able to say to those who conquer and as a result will rule with him, that they will sit with him on his throne that he will sit on when he comes. Then in New Jerusalem is when God's throne and the Lamb's throne are said to be there.
[2 But this man offered one sacrifice for sins for all time and sat down at the right hand of God,]
[31 “When the Son of man comes in his glory, and all the angels with him, then he will sit down on his glorious throne.]
[21 To the one who conquers I will grant to sit down with me on my throne, just as I conquered and sat down with my Father on his throne.]
[22 I did not see a temple in it, for Jehovah God the Almighty is its temple, also the Lamb is.]
[22 And he showed me a river of water of life, clear as crystal, flowing out from the throne of God and of the Lamb]
[3 And there will no longer be any curse. But the throne of God and of the Lamb will be in the city,]
And one day, you, like everyone else, will bow before Him
That is true, but as God's appointed king. That is God's will, he appointed Jesus to be king for a period of time.
