Okay this is an incredibly stupid question, but

If I reset my brushes, will the brushes I've created in Photoshop be deleted? I didn't specifically save them, I only did the "Define Brush" thing (I have Photoshop 7), and me and my stupid head resetted the brushes and now I can't find the ones I created in any file or anything. So, I'm just asking this to be sure: Are they really gone? I'm sorry for the stupid, lameass question, but I'm pretty new at Photoshop and I'm still in shock about what I've done :(.
