Tammy -- We are all here to help. I had Stage IV tongue cancer, bilateral neck dissection for positive nodes, 39 readiation, 8 weeks chemo.
You get through this the same way you get through anything -- one day, one step, one minute at a time. Pretty soon those minutes, steps and days add up, and you are done! The pain comes and goes, and sure there are side effects and discomfort and anxiety, but the folks here really help.
I am cancer free today, and that is a joy. Don't know what tomorrow will bring, but today was great, and I am only 15 weeks out from the end of treatment.
Ask lots of questions, do exactly what the doctors say, and you will get through this.
