How is God a trinity if “God is one”?
Can someone please explain to me how the trinity is not three gods.

I want to make it clear that I’m learning and that I don’t want anything I say to be a stumbling block for others, but I genuinely feel like I’m in an echo chamber. I don’t want to talk about this topic with people I know, as my experiences online have ended with me being treated like an outcast for asking about something I genuinely don’t understand.
I firmly believe in the divinity of Jesus Christ and the Holy Spirit. I think it’s more than obvious that, from a certain perspective, I don’t deny the concept of the Trinity as such—I was raised Catholic and became Protestant. I understand that the three actors can act with a marked independence and that God has a particular interest in emphasizing the distinction between each one. But there’s something I can’t fully understand, no matter how much I try to reason it out: there’s really no exact biblical quote that says they are three individuals, persons with separate minds and identities. The Bible continuously tells us that God is one; it’s explicit.
I think much of the traditional perspective on the Trinity focuses on representing or interpreting the distinction of the Father, Son, and Spirit as persons. This seems to me like it could be a Greco-Roman syncretism with their polytheistic pantheon and the use of philosophy. The influence of Greek philosophy (specially hypostasis) is evident in the texts of the Trinitarian councils. However, the Bible tells us not to lean on our own understanding (Proverbs 3:5), such as philosophy, on matters that belong to God's nature. I fact the understanding of the philosophy of the trinity got a lot of changes and evolutions. I think it’s an idea heavily influenced by elements outside the Holy Scripture, which I believe is complete and inerrant, with no need of external interpretations.
I can say that I used to believe in the three persons of the Trinity… but now i have tons of doubts.
God is not a person. God is a Being.
Within the One Being of God subsist the three persons of the Father, the Son, and the Holy Spirit.
Together, these three make up the One Being of God.
When Jesus was baptised in the River Jordan, all three were present: the Father whose voice was heard from heaven, the Son who was being baptised, and the Holy Spirit who appeared in the form of a dove.
That is why, when the Son died, the Father and the Holy Spirit did not also die. The Being of God was not killed when the Son was killed because the Son is not the Father, the Father is not the Son, and the Holy Spirit is neither Father nor Son.
There has only ever been the One Being of God and there will only ever be the One Being of God.
Expressions such as "person", "Father" and "Son" are used to help us grasp the concept of a complex creator God, although it must be noted that the pre-mortal Jesus was never created, but was active in creation, along with the Holy Spirit.
The best Bible verses to explain this are in John 1:1-5 and 14:
In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it... The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth."
Jesus is the Word. Jesus came to earth to be born of a woman. Jesus was God with us, back then. The Son laid down his life then took it up again and has returned to heaven, from whence he first came.
Edit: To Subsist, within the context of the Being of God, is To Exist, To Be.
Response to additional question: 2 Corinthians 6:18 must be read within the context of the previous verses about Christians not being yoked with unbelievers. They are being told to have nothing to do with pagans and idolatry. Verse 18 is a quote from 2 Samuel 7:14 where God, through the prophet Samuel, makes promises to David regarding his kingdom. God says “I will be his father and he shall be my son. When he does wrong I shall punish him... But my love will never be taken away from him as I took it away from Saul.” David was not God’s literal son. This is the explanation given in the NIV Study Bible notes:
This familial language expresses the special relationship God promises to maintain with David’s descendants... It marks him as the one God has chosen and enthroned to rule in his name as the official representative of God’s rule over his people. ”
The Christians in Corinth are being reminded of their special relationship with God. Verse 16 explains: “I will live with them and walk among them, and I will be their God, and they will be my people.”
Romans 8:14 says that those who are led by the Spirit of God are sons of God. In other words, all who have entered into the new covenant Christ Jesus established are adopted into God’s family. It’s a spiritual relationship. Ephesians 1:5 explains: “In love he predestined us to be adopted as his sons through Jesus Christ.”
There is only one Son of God, and that is Jesus, who brought with him his divine nature which was added to his human nature. Those who belong to Christ are adopted into God’s family as sons and daughters, but not physically. 2 Corinthians 6:18 is about our spiritual relationship with God.
Contrary to the way some may view this question, it is not a "truth" question but a "how" one. "How is it possible," you ask, given that the tiny selection of isolated verses you quote appear at first sight to be contradictory? You are not questioning the truthfulness of those verses but taking them as a given. You are not questioning the truthfulness of the Christian Trinity doctrine (one Being of God subsisting in three uncreated 'persons'), but asking how it is possible that this be so.
It could only be possible if all three who subsist in the one Being of God are uncreated. If one, two, or all three of them had to be created in order to start existing at a given point in time, then the entire Christian faith would be utter nonsense, and the doctrine of the Trinity as gleaned from the Bible would be rubbish. It logically follows that it could only be possible if the Holy Spirit had distinct personality and uncreated existence as does the Word (the Son, who later added human nature to his divine nature in order to become the man, Jesus).
This is where an additional comment is needed, where you stated, "According to these 5 verses, it tells that Jesus was created before all the rest." Your misunderstand of those verses is causing you difficulty in understanding "how it is possible". None of those verses state that the Word (the Son, who later became Jesus) was ever created. This is where you need a grasp of the meaning of the ancient Greek words in the New Testament which have been variously translated into English as 'first-born' and 'only-begotten'. Never in the Bible are words used of Jesus that are to be translated as having had a starting point in time, by being created, or even pro-created. But that is not what you ask about, and I will not go into that here. Fresh questions are required. Let it just be pointed out that those who cannot see the uncreated nature of Christ in scripture, cannot see any possibility of the Trinity doctrine being biblical. Their interpretation of verses about Jesus can be based on misunderstanding what critically important biblical words mean, and may cause them to make serious changes to their own translations of the Bible, to weaken the import of the uncreated nature of Christ, and how "He made everything that was made" (John 1:3), logically meaning that he could not have been made (created) himself. I add this last paragraph to help get you over the 'hump' that prevents you grasping how it is indeed, possible, for the one eternal Being of God to subsist in three equally eternal 'persons'.
