hi ive suffered with anxiety for years now , but since december when i had a major panick attack it feels like its never ending ive ended up at a&e a couplr of times and am at gp s every week convinced ive got something wrong with my heart as my mane symptoms are palpitations , chest tightness, muscle tension but i feel like this from the minute i wake up i feel really anxious all the time im starting to feel really scared that im just going to drop down dead at any minute all so got IBS which isnt helping . just wondering if any one else feels like there in a constant panick attack .
