Gas fumes from car leak entered home, children inhaled?

I have to SUV's, one was parked in the driveway and the other in the garage. I was heading out in the one in the garage. Something I NEVER do, but did this time, was I turned on the truck in the garage with the garage door open. I then put my kiddos in their carseats, and went to move the truck in the driveway to the street. 2 minutes later I came back to the garage & smelled heavy gas. I immediately turned off the truck & noticed I had a LARGE gas leak. The gas leaked all over my garage floor. I took the kids out as fast as I could, and tried to turn the truck on again so I could back it out of the garage. Well, the truck wouldn't move! So now my truck is sitting in the garage (attached to my home) and there is a puddle of somewhat evaporated gas underneath it. Thankfully, the truck only leaks when turned on. So it's not leaking at this moment. I am alone with two kids and refuse to sleep with my garage door open because I'm too scared! So here's my question, or questions...is it okay that my kids inhaled gas for about 2 minutes? Is it okay that the gas fumes from the garage are slowly coming into my home? Am I gonna blow up or not wake up? I'm really freaking out right now and have to wait for a tow-truck early in the morning to get this vehicle to a mechanic. I'm super nervous, can't sleep, and want to make sure I don't do anything that will cause me to explode or make my kids retarded. Thanks!
