Im glad you are speaking to a BC Nurse today @cazgib10 . 
. But make sure you touch base with Oncologist as well. They are the ones who would know definitely if a treatment was unsafe. Even if initially it is just over the phone.
Loads of people are anxious during treatment. Some faint. For many (me included), its a really stressful process. So that shouldn’t be a reason to cancel treatment altogether.
Treatment plans get changed all the time, depending on how people react to side effects. My Oncologist asked if I wanted my dose reduced this week, due to garbage side effects last week. So nothing is written in stone.
I can completely understand how vulnerable you must be feeling though . But my Oncologist said “I need to do what you feel happy with. This is your choice”. So hold on to the fact you do have a voice nowadays.
Chemo is one part of numerous treatments. Sometimes people have a break from chemo altogether, then start again later down the line. In the past they were less likely to alter treatments. Nowadays they serm far more willing to work with us. Assess, review, adapt.
But be as informed as you can be. Its OK to ask questions. Its definitely OK to be an equal partner in your treatment plan. 
Sending you strength and love.
They’re likely weighing up the risk of your neuropathy getting worse or even long term, so perhaps they will try a different drug once things have settled. You don’t want to be left with serious pain because of this treatment, but at the same time you want the treatment to get the best outcome possible. It’s a tricky balance. I agree with the others about seeing your oncologist to have it explained, and hope the chat with the BCN was reassuring. Sending hugs 
and hope you get some answers soon.
