You will have to learn to not push yourself too far. It is good to challenge and push ourselves, but too a degree. Getting sick is past that mark.
I want you to know we support and want to help you. We know school stresses you out and there are many temptations out there to sidetrack you, but you got to focus. You need to take small breaks, don't overload yourself. We are here for you, just a click away.
