I was diagnosed with depression in my teens and tried to kill myself a few times. The number once source of my unhappiness was and still is school.
The bastard school teachers don't care at all that they leave you with no time for your hobbies, or just to relax. They have no issue that maintaining your GPA, getting good college entrance exam scores, extra circulars, etc... leave you with no time to rest and take time off for yourself. If a student develops poor mental health from trying to maintain all of this, the schools are completely indifferent.
That and I had a Mom who yelled and was vicious towards me, in order to have me get good grades.
During my teens, I couldn't turn anywhere to get a break. The school tortured me for reasons listed above, and Mom was horrible to me at home. My only safe refuge was the kickboxing studio, but as prior mentioned, the schools absolutely do not care if they leave you with no time for your hobbies by forcing you to jump through their academic hoops. I had to be absent from kickboxing for weeks just to keep up with school, my only safe refuge where I could relax and be myself.
My teen years flushed down the drain for the education cult.
