What can I do without a high school diploma?

Like the title says, I’m confused on what to do if I don’t get a high school diploma. I’m a sophomore in high school, and it’s already looking terrible. I’m burnt out to exhaustion, I’m sleep deprived, and I can’t even stay focused in class anymore. I have a 1.5 gpa and I’m already thinking about dropping out. I already have some hobbies outside of school, such as making punk music, writing poetry and writing, and I’m thinking about getting a job at a supermarket to try and support myself for a while. I’m also thinking about just joining a trade school.

But before I do any of this, I just want to know if there’s anything I can do to try and calm myself down. I’ve already asked teachers for help but they don’t really care.
