Panic attacks are no fun. They do pass, though.
There's a saying that I've seen used at SMART Recovery, and probably elsewhere, and it is similar to what Lulu was suggesting: think it through. Think your fear all the way through to the end. Imagine. Visualize. Do a rational analysis of the situation.
Then, the simplest thing to ask is 'what is the worst that can happen?' After you've asked that, the next question is 'then what will you do?'
That process has the effect of removing the unknown, which is what we mostly fear, from the situation. It gives you an opportunity to be realistic--not pessimistic, not naively optimistic, just realistic. And it keeps you looking forward.
