I used to get high breaking fevers regularly a few years ago. Nowadays, not so much, although a year ago a 40C (104F) temp while on Remicade got me going to Emergency. The idiots thought I had gastroenteritis, kept me in for a few days, but discharged me without any steroids - I was back even longer a few days later.
Anyhow, fevers are horrible, so I do sympathise. They are extremely rarely dangerous in themselves though. Hopefully this'll reassure you a bit from the medical side of things:

your relationship and possible counselling... :-/
