I've just woken up with a mild pain in my chest. I'm home alone with my 2 children and started to worry a bit 8 felt a bit like I have pins and needles. Heart started to race and I felt like I was struggling to breathe so panicked and called 999. My heart rate on my fit bit registered at 155 and I had noticed earlier today that all week my heart rate has been slightly higher than usual. While on the phone to the operator my heart rate started to slow down its currently 102. I could be waiting an hour on an ambulance. I'm really scared I don't know if I've had a panic attack and this is all in my head. I've manged to write this so if it was serious I wouldn't be able to do that would I? Please someone talk to me and reassure me I'm so worried my 2 children are in bed. Worried something is seriously wrong but also worrying its been a panic attack and I'm wasting ambulance time.
