I am 39 years old. I am an active mother of three teenagers, and have a highly active job. recently I have not been able to concentrate, breathe heavily when I have to any kind of physical excercise, and fall asleep at the drop of a hat. I am extremely thirsty all the time and have blurred vision. All test for diabete s and tyroid have come back normal. I was recently seen in the emergency room for dehydration...but I drink water all the time. Test results showed I have high calcium levels in my blood. They found that I have a heart murmur which is caused by a hole in my heart. What causes this and can all the other systems be a sign of the murmur? They think I am depressed...though I disagree.
