I Had A Reaction While Taking Docetaxel. I Thought I

I had a reaction while taking Docetaxel. I thought I was dying. Couldn't breathe at all. Sent to the ER at Emory. Much better now. Should I continue to take it? My PSA has gone from 3 -8 and so I desperately need the treatment. Do you have any suggestions? My cancer being as a prostate cancer .It was mostly removed during surgery. Now it has spread to my bones.
