...is it POSSIBLE that i have "swine flu"?

There are actually many infections that can have that affect so I wouldn't scream swine flu so quick but it is a possiblility since you've been exposed to others that had it. Many people actually have caught it and recovered just fine just they only like to put emphasis on those that are dying from it. Those people are usually old, really young or have a weak immune system due to diseases and etc. So don't freak out. Treat yourself properly as you would, call your doctor. They'll let you know how to get over it. Also if it does linger too long with no signs of getting better, get checked out.
