what do you do when you know in your heart(and by the decline in health) that someone you love and cherish deeply is about to pass away.. hospice has been caring for him for a few months now in his home and slowly, but surely things have gotten worse. over the past week he has declined immensely and today his nurse told him it's time to go to the hospital and he refused. his oxygen levels were very low, blood pressure very high, completely out of it and unable to function. he only wants his daughter there with him full time and I'm just heart broken. my uncle is my world. he is like a father to me and it's to a point that every 30 minutes of her being gone at the doctor I have to go make sure he is still breathing. and if not call an ambulance. I've got about 15 minutes and I'll need to go and I'm terrified. I know this is pregnancy related but I'm in a state of complete panic and my husband is working late. sorry ladies for the sadness but you all have become my people.
