The trach does suck and I'm sure it does add to your discomfort and anxiety. Doe yourself a favor and tell the nurses. Between them and the Dr's, I'm sure they could send a few Xanax your way.
I've been there. It was and is the worst days of my life. Bear down and focus on becoming cancer free. But don't be afraid to ask for the medications that will help you get there.
Good Luck.
