Is it ever a good idea to drop out of high school?

What about if it was because of medical condition that was progressive and degenerative and school was becoming quite difficult to get through? I'm 16 btw, and I live in GA. I have a condition considered a disability by my state (a mitochondrial dysfunction) and lately school has been getting quite difficult for me heh. Just...ah. This is kinda hypothetical because there is a possibility my health could improve if there is another problem being currently tested for due to a spinal tap. I'm a sophmore in high school and I'd want to at least get the rest of this year done, I just want some opionions on this. :s
