I duno what's wrong with me even if I feel sick I think I'm dying if I have a sore throat I'm thinking it defiantly must be cancer if I have a headache I must have a bleed to the brain in my heart beats fast that means there Deffo something wrong with the heart. I just don't know why I keep thinking this way. I was fine never thought like this. I was a normal teenage girl , then one night I was laying in bed had a pain in my chest n I run down the stairs to my mum and I thought I was literally dying so did my mum I called the ambulance but that's when I had my fist ever panic attack and from then it's ruined my life constantly worrying about my own health and I can't get it out of my head. Right now I got a burning sensation in my chest and I keep burping and I get sick in my mouth does anyone get this?
