more than likely, i just remember hating school but doing my work anyways to please my parents and not making friends discuss
that's because you were immature. happens to a lot of kids who are not loved by their parents, badly raised who dont understand/take pleasur einto studying while being kids, adolescents. It's parents faults. They are suposed to teach you that school is important and can be enjoyable.
These kids are not mature enough at the right time and are less prone to suceed in life later as a result. You re now supposed to be more mature and should enjoy studies more. You could re-discover sudying. It would improve your life tenfold instead of wasting your time painting and surfing the web. You also sound very lonely, this too can be modified, but hurry up dude, at some point you cant change anymore.
