I'm 15 and i woke up today feeling dizzy, nauseas , and off balance and that was at 6am. Then i slept some more and woke up around 11lol but still feel the same but worse. I felt as if i was going to throe up but i didnt. I was born with heart problems nd recently started feeling pressure in my head, hot flashes, tingly feeling in my hand leg and feet, and today extremly nauseas and dizzy. Couldn't even go to school todau
