First Allergic Reaction

Have you ever had an allergic reaction? I did once. If was scary, very scary. I ate some food that contained peanuts or tree nuts at dinner. After that, I felt fine and I went to bed. In bed, I started to feel kind of weird. Then I knew that something was wrong. First I felt hot. Next, I started to have difficulties breathing: I couldn't breath properly! Then I puffed up. My mom called the ambulance. The firefighters came first and started to help me breath by putting an oxygen mask on my mouth and nose. Then the police came and when the ambulance got to my house, I was put onto the bed. In the ambulance, I got a stuffed animal. Then I fainted. When I came back, I was in the hospital. I was on a platform and they brought me into a room. I fell asleep. When I woke up again, I was in bed at home. My mom told me that I was allergic to any type of nuts.
I don't want to have an allergic reaction again. Even if my mom says that a food or a snack doesn't have peanuts, I always check anyway to make sure.
