Lately i often feel that my heart's going to stop. I cant sleep well at night and often woke up terrified in the middle of the sleep as if my breathing and heart's gonna stop. I have not been working since October as i cant focus on my work and i cannot sleep early and wake up feeling lethargic. This lately i keep on feeling that my heart is going to stop any time and soon after my blood pressure will increase and heart will start beating fast. Only my sister understood how i felt. My husband will just ignore and take it as if nothing happens. Im often left alone at home as he is working shift.
