Hi Loana. I guess never say never, huh? What you are describing is extremely rare. Panic attacks rarely end in people passing out. You should probably talk to your doctor about your experience to find out if you have two separate problems, a panic problem and a fainting problem. Your doctor will probably want to know in detail what you mean by "pass out", such as do you mean that you get really exhausted and fall asleep or do you faint away? Have you ever hurt yourself? For instance, has your fainting ever caught you by surprise so that you have fallen and hurt yourself when you pass out? If there is any good news it is that it sounds like you seem to see it coming and have time to prepare.
Sometimes you see a fear reaction like this in small kids when they get really frightened or overwhelmed by an experience, they get really really tense, and then they just kind of shut down, but it looks a lot more like falling asleep than fainting away.
Adults most often faint when they have a blood (or injury/needle) kind of phobia. I've seem only a couple of these in the hospital over the years. Hopefully somebody in the support group can relate, but this kind of problem is pretty rare. The bottom line is that you should discuss this issue in-depth with your doctor.
