Is your school aware of the health issues that you are having? Rather than struggling to do the same amount of schoolwork that kids without those issues do, perhaps they could work with you to create a plan that would be more manageable for you while you are dealing with these health issues - an IEP, or individualized education plan, as it's called in some places.

Maybe they could give you more time on assignments, or maybe they could give you more assignments that could be accomplished independently, at home, on days when you had to take off for physical health problems.

If you haven't looked into that, I would seriously consider discussing it with the guidance counselor at your school and possibly some of your teachers. Even if perhaps you were not eligible to create a formal IEP for some reason, they could make informal arrangements with you where they could.

Maybe you could come early / stay late at the school and meet with some teachers individually on days when you were able to come in to review what you may have missed on days you didn't.

Maybe you could consider attending summer school - I know no one likes to waste their summer in school, but it might be a great way to make up credits you missed and get more individual attention than you are getting now.

Maybe you could also look into online high school education programs - I don't know anything about them, but I hear they have them now and I see advertisements for them sometimes on TV and the internet.

Maybe you could hire a private tutor to work with you in the evenings / on the weekends.

I also agree with the person above to try seeing your doctor and seeing if they can recommend any way for you to be healthy enough to attend school on more days.

Those are just a few suggestions. I think it's great that you are thinking about your future and that you posted here for advise suggests to me that you are really serious about getting into the college of your dreams and doing whatever it takes. It seems hard and sometimes even unattainable now, but try not to let your illness or your frustration get in the way of doing what you have to do.

When you are feeling like you want to give up or would just be better off dead, remember that you made it to your junior year already and that that is farther than some people ever make it in their lifetime! I know that you can find a way to do it. Just don't give up.
