Hi 

it's totally normal to feel like that .   You want to get the testing and results done yesterday .   The waiting for results is the worst  so try and have some fun .  It's hard I know but think of it as no need is good news .   I was a career for both my parents first experience was terrible with my mum but luckily different with my dad .    Contact your dads gp , see if you can speak to someone who is dealing with it and chase up your appointment.

hope your dad will be seen as soon as and wishing him good health
