I am having an extremely intense schedule this period that is leaving me depleted of energy

I had a couple of days of that I have been holding onto and expecting to relax. Supposedly we would spend them with boyfriend. He got sick. And i am mad. As if he did everything he could do in order to get sick. I know it might sound egoistic...but while he knew how much I needed this weekend and how i have been expecting it, he got an offer for an extra job on a beach just three days before my days off.
He already has a job, he works in the military, he is also studying to be a chef in the afternoons and then he had to take this extra job, beach related. He got terribly burnt as he didn't pay attention, despite my sayings on the phone and now he's sick with high fever.
I am desperate. I can't take care of him as i feel too close to a mental breakdown and I don't know how to calm myself down. I was so invested in this weekend and after that my intense schedule will have to go on.
On top of all these i feel like a terrible human for having my man laying there and being such an arse. But i feel trapped. I would like some support, to be taken care of and not to have to care for another. At this moment, i am thinking of all the caring i have done in my whole life and the so little i have received and been taken care of.
