The meaning of life.

Here are my thoughts, my meaning of life. Perhaps a little, or perhaps too selfishly.

I'm still a schoolboy, only in 8th grade, and I'm terribly unhappy with my life. It's not that I dislike everything; I certainly have interests, friends, and favorite activities. But on the other side of the scale, there's a much heavier burden. First of all, this is, of course, school. Many, especially adults, will simply laugh at these words. And indeed, it sounds funny. They overload me with lessons, which are absolutely unnecessary for me (except for a few specific subjects). I spend a lot of time on them. I have a weak will, I'm a terrible slacker; I really want to spend all day doing my own things, but because of lessons, because of a bunch of extracurricular activities (one or two per day), because of the distance learning for math that my parents are forcing me to do, I don't have any time at all.

The meaning of life is to live it beautifully and die at the end of the road.

There is meaning in living beautifully, but again, the beauty is overshadowed by all sorts of chores. It was good in kindergarten. Spending all day doing nonsense, without worrying about anything. But 8 years have passed. For now, I don't see the point in living.
Adults say that school age is the best time of life. However, I can't understand where the "best" is, where the "days" are, and where the "life" is. If I feel so bad now, what will happen when I grow up? It's scary to imagine. Some will say that you need to study well now for a good life in the future. Let's say I studied, got a higher education, a high-paying job, but why? The more money they give, the more you have to work. And again, there will be no time to satisfy spiritual needs. And if I didn't study well, didn't find a decent job, then there seems to be a lot of time, but how to spend it? My needs are expensive, but there is no money.
Some will say that you need to live for someone. Adults have children, husbands, wives. And even teenagers have girlfriends and boyfriends (unfortunately, I don't have a girlfriend yet. Maybe that's why I don't understand). And you need to live for the sake of your descendants. So that they end up in the same situation of searching for the meaning of life? So that there is more burden than pleasure?
Maybe the meaning of life is in searching for the meaning of life? And what about the meaning itself, excuse the pun? To find this meaning when dying, and before death, to be saddened, realizing that all his life a person was striving for something that he shouldn't have?
In the previous post, it was written that a person is a link in the improvement of humanity. But why improve it? If there is no meaning in life? Otherwise, it will be a vicious circle.
Conclusion: there is no meaning in life.
Perhaps I was even terribly selfish. Perhaps there are gaps in my logic.
P.S. I haven't found the meaning of life for myself; I don't know what it is for others (although why not know? I can read the topic).

P.S. I'm not going to commit suicide)) apparently, I'll have to live with the false meaning of life of searching for the meaning of life.
