I have suffered with health anxiety for years now been trying to get back on track . My fear is heart related where every pain or weird sensation in chest has to be heart attack or heart failure. I get weird popping sensations in chest or it genuinely feels like my heart or chest vibrates it's horrible. I'm scared all the time I get palpitations all the time just need a bit of advice please. It also feels like my heart is being squeezed but doctors put it down to anxiety all the time. Xx
