Hi Iain.
There's no need to feel embarrassed. You're experiencing something that is terrifying and out of your complete control.
Of course, you need to be positive, but sometimes its ok to have a meltdown and become a blubbering mess.
I used to do it when my husband was out. But sometimes I had no control over my feelings and reactions. I used to get the runs eveytime I heard the oncologist's voice in the Oncology Day Centre!
My friends were beautiful and compassionate, however, they held their partners in bed at night, not feeling the horror thatI felt. They get to walk away from the disease and its friends, while we are immersed in it.
Iain, it's ok to fall, as long as you get back up and keep moving forward.
Sending you positive vibrations.
