I really think its gonna kill me this time. The last few days my heart won't stop fluttering. Its so bad that I really lose my breath sometimes. Lightheaded as soon as it hit knot in the stomach and pain in my arms. I just can't handle this any more. I've even noticed the last few days when falling asleep be it night or day I find myself jumping out of bed short of breath and a pounding heart. It feels like my whole body goes numb and I stop breathing. I'm terrified I'm going to die in my sleep! Well honesty I'm terrified Im going to drop dead any minute of every day.I really need help!
