Hello TrevorL,
It would only be natural to be apprehensive of the treatment and recovery road ahead. After inventorying my fears, I prayed for strength. My takeaway was to just try to take care of the business of the day...just get through the day. You mentioned deep breathing helped you through the restrained radiation session. I did the same thing and framed it mentally as a form of meditation. Again, what helped me was just keeping in mind that I only need to take care of the business at hand today....no matter what it was. I made a lot of protein shakes and amino acids, high calorie soups and pastas and did was able to get through without the PEG. Please ask your support for help when you need it. I was given medication for each malady that came up. Stay strong. I got through it (even worked a couple days a week) and you will, too.
