Is my ankle broken?

Rolled my ankle while carrying my 3 year old today. Hurt pretty bad, but toughed it out. Later in the day was in a gym on the bleachers and when I stepped off about 1 foot down the pain came and I started limping and the pain increased with every step. Now it's extremely swollen and I can't even sit on the couch with my feet on the floor without it hurting. I'm borrowing my brothers crutches for the time being. I, like one of the other users on the site, do not want to sit in the emergency room for a long while with the kids. I'm not sure what to do. Guess if pain and swelling stays, I'll be on my way to the doctor. So...broken or sprained??
