My Dad is in hospital. I won't go into details about why, but essentially the thing that's wrong with him is really painful and as a result he finds it hard to breathe. (His lungs are already poked from years of smoking, even though he stopped over 20 years ago.) So he's taking only tiny wee breaths and can't get enough oxygen but he's too scared to take big breaths cos it starts him coughing and that hurts and then he gets scared because he can't breathe. Kind of a vicious cycle.
It hurts to see my big strong Daddy look so weak and small.
