TPF Induction Chemo to being tomorrow a.m. and I am freaked? Anyone with advice for a newbie here?

I have to have four days, 24 hour of TPF Induction Chemo beginning tomorrow. Need some advice desprately as I am so upset. I have already had SCC Sage IV in my tongue removed and now a tumor growing around my larnyx, trachea, carotid artery, thyroid and esophagaus. This is what they feel will help shrink the tumor so as to avoid the most destruction by surgery.

Please explain what I will experience tomorrow if you can.

Thank you somuch for your time.
