I dropped out of school when I was halfway through grade 12. One of my best friends had died the summer before going into grade 12, so i was really depressed. I became a huge stoner and was failing all my classes because i didnt do jack shit...i didnt have a lot of friends, and the ones i did have were just like me, so we always cut class and smoked up. I was incredibly depressed.
I dont regret dropping out at all. There was no way i was going to pass...and if i did, it was going to be barely scraping by. I was just not ready to graduate, and grow up.
I got a job and worked, partied all summer, had my fun. When september rolled around, i was ready to go back to highschool and finish. It was great because i was actually ready to learn. I quit smoking pot and actually got good grades, and met some cool people. The gradding class i was with the year before was NOT a nice group of kids, but these kids were really nice, and much more mature.
If you just want a break from highschool, but plan on graduating..then yeah, take a break. Not everyone is ready for everything at the same time...i didnt grad till i was good and ready. But DO graduate eventually, whether its through homestudy, or whatever.
