I also disliked school/high school (in part because I got bullied).
I wasn't so good, but after a lot of efforts I finally finished it and gone to university (I'll talk about it later).
I know it could look counter productive but I redone my first year of High school, and my student life become better. First, my bullies wasn't in my level anymore so they stopped annoying me (almost), second because the courses became reviews, so it was way easier to follow in class. Also, there was a new effect of being "the older one" of the class that helped a lot at beginning to make friends.
After High School, I gone to university to do something I really like (For information, I paid 7500€ each year, and this university is only for my job domain). It was a very great experience. Everybody here had same passion as me, so it was easy to make friends. The university courses was what I liked, so it was not too hard for me to learn and progress, and today I do the job I want to do.
However, some of my schoolmates was in that university because "they had to...". Most of them didn't finish the cursus and just lost their money. This means debt, lost time, and hard time to find a job that is finally not what they expected.
I cannot advice you to go to university just because "it is the way to find a good job". The best job is not the job that pays the most, but the job you like to do. Maybe you'll not have a great salary, but if you do what you like, it probably doesn't matter that much. Would you really want to wake up every morning to do something you hate ?
