Feeling overwhelmed and anxious

I had a different chemo regimen than you so I'm not sure how that impacts.  I was advised to have a port by the oncology team before I started.  Although I had significant problems the first time they tried to access it (poor needling that didn't show up in an x-ray) and I hated the thing, I am also really glad that I had it.  It made the whole process so much better and it saved the veins in my arm.  Given I can only use the one side for needles, it made sense.
