Hi, I'm 15 ( 16 in a month ) and female. I'm 5 foot and when I start to think about my breathing, I start struggling to breathe. I feel as if I have to make myself breathe manually and then I start to panic and think I'm going to pass out or faint. I don't get any pain or anything like that but It randomly occurs for example I'll be sitting in bed or lesson and I'll suddenly think about how I'm breathing and this happened everyday or at least twice a day. Why does this happen and how can I get over it ?
