peanut allergy

I've just had such a bad experience. Worse, I caused a small child and her parents to have a terrible experience. Remember I have friends who are "perfect women"? We went to a July 4th BBQ at PW's house yesterday. It was such a sweet, traditional but with the flair only PW could provide backyard party. The conestoga wagon used for the Christmas party was now holding our potluck dishes. I agreed to bring a large container filled with ice and drinks, but I didn't feel that was enough, so the day of the party I whipped up some cookies, knowing there would be a lot of children at the party. We had been there about 20 minutes when my daughter came to me and said that PW's daughter ate one of my cookies and was sick in the bathroom. My daughter followed up with, "Mom, she has a peanut allergy!" I ran into the house to find PW in the bathroom with her daughter, her husband on the phone to 911 and the grandparents hovering around discussing the contingency plans. The daughter ate a cookie, started having problems (Anaphylaxis) and tried to hide until her friends got help. Her parents gave her some benadryl and an epi shot and we watched her to see if we needed an ambulance. Once the initial panic was over, PW and I sat down and cried. I still can't believe I brought toxic cookies to her house. I knew her daughter was lactose intolerant, but I didn't know about peanuts. Still, I should have checked in with PW. I was just working on auto-pilot, just making some cookies. PW said she was surprised that I was the one to do that, because my family has so many health issues (true). That was it for me, I couldn't stop crying and when the house cleared, my family and I made an exit from the party. We went out to dinner and I cried through the whole thing. PW called and asked me to come back, but I told her we were finished for the night. This morning I called and apologized again and spoke with PW's daughter who is fine and was very sweet. They've invited us over for left-overs tonight, which I think is really nice of them. I hope the grandparents aren't there because I honestly think they wanted to murder me.
