Everyday I'm convinced I'm dying! I've been feeling so ill for about a month now, constantly feeling nauseous, headaches that I think are a brain tumor or anuerism, weakness, tired all day and overall mentally not right which makes me think even more that I have a brain ailment, I'm constantly scared. I've gotten multiple blood tests, ekgs, echo, 24 hour monitor, urine tests to find everything normal but I'm really convinced I'm physically sick and thinking I'm gonna die. I was also experiencing some derealization and tingling in my hands and feet. I am seeing a therapist and getting on medication soon that will hopefully help has anyone experienced this?
