@sfr09 The first few weeks are the hardest. Once you get started its like a massive roller coaster ride, but you will come out the other end.
I was diagnosed in Feb 2016 and had 4xAC and 12xpaclitaxol/carboplatin. I also had chemo first which I think is fairly common these days. That way they can tell if the chemo is working and also gives you a chance to think about surgery. My chemo got rid of my lump but then I still went a double mastectomy as found out I was a carrier of the BRCA 1 gene.
I also used the cold cap for my 16 treatments. It was hard work and pretty gruelling at times. But I felt it was worth it. I was lucky enough to keep the majority of my hair. I only had a little thinning which was barely noticeable.
Good luck and and happy to answer any questions if you have any x
