35 y/o and diagnosed with HER2 positive breast Cancer

Hi there, I'm 41 and recently diagnosed with stage 3 Her2 positive breast cancer.  I had my son young and he's 17 now but still, I was planning a lot more of my life once he finishes school and now I have to fight for my life!  It's terrifying but we're both going to beat this, you and me!  We have Herceptin, and we are so lucky to be in Australia, not America where you will go into bankruptcy and not be able to access the medicine you need.  I'm at the beginning of a chemo journey which is not what I wanted to do, how can you choose between poisoning yourself or chopping off a part of yourself?  Or most likely both!  But you just choose life, it's all you can do. It's a shitty hand to be dealt.  But I will tell you that chemo isn't as bad as I was afraid it would be.  And I'm really hoping my tumour shrinks a lot so I can have a lumpectomy instead of a mastectomy. It must be really hard for you with your little kids.  I hope everyone around you is spoiling you and looking after you.  My sister visits me and cooks and cleans for me when I'm not well.  I hope you have that kind of family and friends too.  xxx Take care
