Hi , I was diagnosed with HER2 Postive breast cancer in December 2014. I had chemo, full clearance of lymph nodes , reconstruction, and radiotherapy. And one year on  Herceptin. Also will be having reduction and uplift in other breast next year .  I have been mostly Postive through the treatment. I have dealt with the treatment one step at a time. It is when the treatment is finished you start to realise what you have actually been through. This is personally when it effected me. I think this was the adjustment of coming to terms with lots of emotions . For me I told myself I can make a choice , either I can carrying on worrying about what if or I can now move forward and enjoy each day. Yes there will be still times I will think about has we all have side effects from the  treatment to be reminded from but  I don't want it to take over my life any more . I know everybody has there personnel journey and we all have different ways in dealing with it . But this is how I was able to deal with my journey. I hope this might help anyone. 

I think you hit the nail on the head when you say about worrying it's a scary feeling! I was diagnosed in October last year had lumpectomy followed by the chemo and radiotherphy which I worked all through treatment it's only now that treatment has finished and the tablets I'm on are falsing the menopouse on I'm struggling which to me makes no sense!  like you say we must stay positive though - thank you
