I've given up trying to find a job
Why would you want to give up finding a job?
It's a war for me, where there is thousands of people competing with me.
It is hard to find a job especially with so many other people competing for the same jobs but you need to work. Otherwise you won't be able to eat or have a roof over your head.
I can earn money through illegal activities.
Don't do that, you will go to jail. You should talk to a career counselor and try to get advice to help you find a job and stand out in the crowd.
