What should I do now ?

I had swine flu. After that, I appeared for both the SBI PO and IBPS exams, but on both occasions I suddenly developed severe breathing difficulties. Since then, it has been a month and I’m still having trouble breathing. The medication also makes me dizzy, so I couldn’t prepare for the Mains exam properly.

I scored 57 marks in the SBI PO prelims, and I had lost hope regarding IBPS as well. But now I’ve been shortlisted. I don’t have much time left, and given my physical condition, I don’t feel capable of giving the exam to the best of my ability. What should I do?
