Hi , I have had health anxiety for 5 years , it started with a relationship break up and the fear that if anything happened to me my poor kids would end up with their dead beat dad !! , anyway it's always been cancer I have worried about , in fact I had self diagnosed every cancer possible - until a few months ago when I had my first palpitation out of the blue and felt my heart actually miss a beat , now I'm terrified my hearts not good ! , I can go a few weeks without any and then like today when I'm home alone trying to chill I felt suddenly anxious and then had palpitations and felt skipped beats for an hour, and fell waves of warmth in my chest ? they settled and my heart beat is now stable and regular, I've booked doctors for next week but any one else experienced this ?i am sure it's anxiety and google has helped ( for a change) by saying it's really common , but it scares me , anyone else ?
