The other night I was about to go to sleep so lying down, and out the blue I felt like I couldn’t breathe, my heart was racing and I got the feeling I was going to faint (fainted a lot as a child so I know and hate the feeling!) My chest was tight and couldn’t get a deep breath
Ended up ringing 999 as it was terrifying and I was on my own but it did pass. Went really shaky afterwards
Last night, similar again, lying down just before sleep and my heart starts racing and felt like I was short of breath
Have had panic attacks before but not for years
