Does any one else have this happen. I have panic attacks daily it feels like. I always feel like I'm going to fall over and die, If I get a headache I'm dieing if I have chest pain it's a heart attack and I'm dieing today my head felt so heavy and I was really dizzy I also have some derealization episodes I must have brain cancer and I'm dieing. How do I redirect myself how do I cope I'm at a loss. I do have a low dose of xanax but I feel like it does not work sometimes.
