Panic Attacks And Agoraphobia

I've been dealing with anxiety/panic attacks for the past few months, and i'm kind of starting to feel like I have things under control. Once the symptoms start, I try to control my breathing, and things usually don't get worse. But i've been fighting panic attack symptoms off for the past few nights, and today I went somewhere that was only an hour and a half away, and has this nonstop feeling of nausea and lightheadedness. What do other people do who have this problem of being afraid to go places farther from home, because of fearing you'll have a panic attack and won't be able to stop it? Ugh, I think i'll just stick close to home from now on..
