Hi Mandy.
I think we've all been through that absolute shock, and feeling of disbelief that this is really happening to me. Then your mind can just spin out of control, and before you know it, you've constructed a 'story' about the outcome. But that's what it is: a story. At this stage, you really don't know what is going to happen, so I think it's really important that you deal with what you DO know, and try very hard to stop your mind inventing steps and stages that haven't yet happened. Often what you fear doesn't happen, and what you haven't even thought about does happen. Either way, we somehow find the strength and the support of those around us to get through this nightmare. And it is a nightmare, but you are not alone.
I was diagnosed with an 11mm grade 2 tumour in June 2013. It hadn't spread, and I had a mastectomy and reconstruction. No chemo necessary. I've chosen not to take Tamoxifen as my cancer is 'low risk' and the oncologist told me that I was 'most likely' cured with the mastectomy. So try to just hang in there, stick with the positive information you've been given. If your ultrasound suggests it's localised, you should focus on that. 14mm is not a big tumour either.
One other thing:
When I was having a biopsy, a lovely nurse said to me: You must just take this one step at a time. So I did. Got through two operations and focused only on that. Got through the physical recovery and focused only on that. Got off HRT and focused only on that. Now I'm dealing with the emotional fallout of the whole thing and am getting through that. I firmly believe that we can't get our heads around this whole trip at one time - it would be too overwhelming.
So please just try to take it one day at a time. Try saying "I'm parking that" if your mind starts spinning out. Try to focus on the things in life that are still beautiful. Your kids. Nature. Sunshine. Flowers. Music. Whatever it is in life that you love and that is important to you. it will still be there when you come out the other end of all of this, and it can really sustain you in the meantime.
And look after yourself. I meditate and do yoga, and found that really helpful. I also treated myself to some lovely soap and body lotion, and found it was good to look after my body as well as my mind and spirit.
Just hang on in there Mandy. You will get through this. You will find the strength. You will fall over sometimes - we all do - but you will get up again. And you'll find incredible support from the ladies on this site. I think they're like a flight of guardian angels, and we all need those, don't we!
Best of luck, Pam
