I don't know. I had a fight with my older brother today and he got up in my face threatening to hit me and pushing me and he kicked me out. When I went upstairs to get changed (this was in the morning so I was dressed) and I don't know if it was because I was crying or what but I couldn't breathe and I was really hot. I kept choking/gagging as if I needed to be sick. It just scared me. This type of feeling has only happened once before at random whilst I was at work.
