OK I am 16 and first i went outside with my friends to shovel the driveway. After we shoveled for like 20 minutes I decided there was too much snow and that we should snow blow. After finally starting the snow blower I started to use it. When I went to turn the shoot I got a mouth full of gas vapor or something. I started spitting. Then the snow blower started to smoke. I turned the snow blower off but I got really scared and I came inside the house. Then I was shaking, crying, and I felt like I couldn't breath. Now it has been like 20 minutes since I came inside and I still feel like I can't breath (but deff. not as bad as when I came inside), my neck hurts (I think I strained it when I was shoveling it), I still feel like crying, and I smell like gas. I have a history of having panic / anxiety attacks too. Any suggestions for me to feel better??
