Is it possible to drop out of high school and re-enroll a few months later?

I’m an eighteen year old senior. I’ve always dreamed of graduating, to make myself and my parents proud. I’ve never struggled with going to school until this year. Suddenly, I don’t feel like even getting out of bed. I’m not being bullied or anything else, I just lost all desire to go to school. I was wondering if there would be any alternative to school, such as computer courses, that I could take for a few months but still graduate with my class? I don’t want to just drop out with only months left of school, but I’m completely bored with the whole high school scene. Any ideas would be appreciated.
