I am here to tell you that you will make it through! My dad finished his 30 radiation treatments 5 weeks ago and he is doing so much better! Yes it was a rough go. It hit hard about week 3 and he wanted to quit. The main thing I can tell you is to get pain meds. Also the peg would be a good idea before radiation starts as a back up plan for nutrition and hydration. Also keep looking to the future because like I said my dad is doing a lot better now and I can see his strength improving every day. Try to put some extra weight on in the next 10 days and know that you can do it and you're not alone!
