I know you love your family and they love you, but they majorly do not get it. This isn't something like elective plastic surgery that can be postponed to accommodate the schedules of those around them...this is life threatening.

If you need to go, go, and there's plenty of us here who hate hospitals but still think you need to at the very least go to the ER( and be as honest with them as you have been with us...know that's not easy when when you are actually sitting there, so easy to prevaricate and minimize) and get checked out. the ER will call your doctor and talk to him and your family will deal with it.
