how to know if you have anxiety or heart problems ? I have this weird feeling like I'm aware of my heartbeat and forgetting to breathe sort of at first I thought it was from these nescafe latte sachets cuz my sister had some breathing problems from them but I have been a little bit stressed out as well then I thought it was from too much caffeine and I have refrained from caffeine but had my first cup today and this heart breathing thing has got worse can someone please help If they have anxiety and what it feels like ? or if it sounds like health problems thankyou
