What you want to do is see a therapist who specializes in CBT. The theory behind this form of therapy is that, yes, it makes it worse to avoid, but in order to face it you need tools to make you more relaxed and more willing to try again when it's hard. Now, as to how people fare, we're different -- some get better and the problem goes away, some don't. But you'll only know if you try, and you can only really try if you can demystify successfully the feeling of panic.
