Sacred Haven of Debauchery

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 and foremost, it's school, of course. Many, especially adults, will simply laugh at these words. And indeed, it sounds funny. They overload me with lessons, most of which are completely unnecessary (except for a few specific subjects), and I spend a lot of time on them. I have a weak will, I'm a terrible slacker, and I really want to spend all day doing my own things, but because of the lessons, because of a bunch of extracurricular activities (one or two per day), because of the distance learning math course that my parents are forcing me to take, 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 silly things, 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 "time" is, and where the "life" is. If I feel so bad now, what will it be like when I grow up? It's scary to think about. Some will say that you need to study well now to have a good life in the future. Let's say I studied hard, got a higher education, and a high-paying job, but what for? The more money they give you, the more you have to work. And again, there will be no time to satisfy spiritual needs. And if I didn't study well and couldn't find a decent job, then there's a lot of time, but how should I spend it? My needs are expensive, but I don't have any money.
Some will say that you have to live for someone else. Adults have children, husbands, and 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 have to live for your descendants. So that they end up in the same situation of searching for the meaning of life? So that they have more burdens than pleasures?
Maybe the meaning of life is in searching for the meaning of life? And what about the meaning itself? So that, when dying, you find this meaning and, before death, regret that all your life a person has been striving for something that is not what he should have been striving for?
Some believe that a person is a link in the improvement of humanity. But why improve it? If there is no meaning in living? Otherwise, it will be a vicious circle.
Conclusion: there is no meaning in life.
Perhaps I was even terribly selfish. Perhaps there are flaws in my logic.
P.S. I haven't found the meaning of life for myself; I don't know what it is for others.

P.S. I'm not going to commit suicide)) I guess I'll have to live with the false meaning of life, which is the search for the meaning of life.
