Forced marriage

In about four years, my family will marry me off to someone I don't know, and I'll have to live to clean and cook for him. I tried to enroll in the most remote university to avoid this, but they wouldn't let me. I tried to work, but they wouldn't let me. I tried to work online but i'm not allowed to have an account, what do i do , i just want to die, I have no way out; women are not allowed to live alone here, and I have no source of income or any basic knowledge that would enable me to escape.
