Me venting about having no friends

It was always difficult for me to create friendly relationships that last longer than a month.
Have you ever met a person exactly like you, you chat with them, joke around, and just spend time together. But after some time, all of this starts to bore you. You stop talking to them, joking, or simply interacting with them whatsoever.
In the end, they just stay in your friends list, waiting for you to delete them.
Then you find another person with similar interests and the cycle repeats.
At some point, I got so tired of this that I stopped having conversations with people at all.
Now I am somewhere far away, watching how everyone else enjoys life by communicating with each other.

This has affected my mental health very strongly. I think the reason for all of this was my lifestyle.
Since the age of 6, I have been flying to many different countries.
In a regular school with a normal social environment, I was only able to study for 3 years until the age of 10. Then coronavirus started. I switched to homeschooling. Then I flew from Ukraine to Turkey. Contact with peers completely disappeared. Because of some problems, we got stuck in Turkey for 2 years. After 2 years, my family was planning to return back to Ukraine, but the war happened. I no longer remember why, but we flew to the Dominican Republic. Another year passed. My sister flew to study in Britain, and my mother and I flew to Canada.
I am 13. I went to 8th grade in Canada. I studied English almost my entire life. Despite this, I did not communicate with anyone at all, I did not know how to start a dialogue.
I am 14. I went to 9th grade. In the first semester, I barely communicated, in the second semester I began to adapt better to communicating with people.
I am 15. I went to 10th grade. The end of the first semester is approaching. I made "school" friends. We exist for each other only when we are at school. This does not really upset me. As always, they get boring to me very quickly, and contact with them only at school is more than enough.
But all of this is not it.
My mother asks me why I am still not interested in having a girlfriend. I ask myself why I am not interested in people. Am I really just destined to be like this my whole life? All this anger began to form a shitty character. I began to envy the people around me. If someone is better than me at something, smarter, more charismatic, more extravagant, I definitely must surpass them. When I remained the only best of the bests, nothing except emptiness did this give me.

If I remain the only person on Earth, I will be the winner. All that will remain for me to do is jump from my twenty story building and smear my brains on the asphalt pavement of the sidewalk.
