People have given you some good advice here Fitzy. My two pennyworth is - there is no point panicking or worrying until you know the truth of the matter. You wil only make yourself ill, or worse!!!
Try to stay positive at this time (easier said than done, I know.)
Try to sort out the situation calmly - if you discover that it was a false alarm, you have done all that worrying for nothing. If, sadly, the facts go the other way, then, I'm sorry to say, you found out in time and you are better off out of it.
Hope that helps - good luck!
