I want to drop out of high school
What makes you want to drop out of high school?
The feeling of being cornered all the time is killing me
You should try to finish your high school education so things aren't harder for you in life. You can decide not to go to college if further education doesn't suit you.
What will I do if I drop out of high school? How can I get a job that pays good money?
Those are very good questions, and they underline the importance of finishing high school.  While you may not need, or desire, to go further and get a college degree, the fact is that not having a high-school diploma will hurt you in the long run.  You could always talk to the school counselor if you are feeling troubled.
