Everyone is different. I am new here but I have still yet to talk to someone whose treatment plan matched mine exactly.
I never went to chemo alone. In hindsight, I could have done the first two (out of 3) alone. I stopped by the office for radiation on the way home from work for the first 2/3 of treatment. The final 1/3 I was on pain meds that would have made driving dangerous.
That said, I would encourage you to allow people to help you. It took me a while to do that because it wasn't my nature but everyone who went with me for chemo and rads were so moved by the people they met.
