Anyone had to stop their chemo ?

I stopped paclitaxel. I completed 11 of 12 weeks. I was admitted to hospital at week 10 for anemia and tachycardia. Week 11 I had adverse immune response, it seemed my body had developed an allergy to the drugs. The oncologist decided to skip week 11 and next week I start AC fortnightly cycles (x4). As people have said paclitaxel is more gentle and AC is more aggressive, I don’t see how I will get through 4 cycles. For the last 3 of paclitaxel I was treated for shortness of breath, tachycardia, and anemia.
