I agree with @dolphina3 when she says the fear goes away after your first treatment and you know what to expect. Each drug regimen is different and you may find that it is pretty easy. I don’t know where you live but here in Oregon it is hot in the summer and I kind of embraced my baldness.
The port is awesome, it keeps them from having to find a vein every time and helps protect your veins from damage too.
I agree with everything @dolphina3 said above, and I would add that this is 12 weeks. Three months of hardship and I pray it buys you at least the 21 years my treatments have bought me. My initial regimen was a year (the bad old days, lol) and I am still here, still doing most of the things I love. I was almost the same age as you when I started.

Will you please come back here and share with us how you are doing?
