So I'm gonna post and ask here because I'm upset and nervous. My husband was working on fixing the lawnmower in the garage and finally got it working. He had it sitting next to the garage just blowing exhaust all into the garage and it was seeping in through the garage door (through the cracks, we don't have good weather stripping there) and I was in the kitchen next to that door for about an hour. I could smell it a lot coming through so my husband said to close the garage down. I opened the back porch door to kind of air the house out but the air is so stiff and dead and there is no breeze, I don't think it helped at all. I feel dizzy and started sweating, I think I breathed too much of it in or something. Or maybe I was just tried and hot. I don't know. My kids and husband seem fine, the baby was sleeping in my room with the door shut most the time. I'm a compulsive worry wart and severely health anxiety ridden....should I be worried?? What should I do???
