Hi SqueakyPea,
I too am sorry you have been diagnosed with this horrible thing. I agree with Kathryne about talking to your breast care nurse for help on a support group for your parther - also one for you. This site is great for all of us, though there is nothing like having someone close to talk to about what you are going through.
Yes, I have to agree also about the crying. You are young, and vunerable right now so cry and let it out. The tears may not stop for a while, so don't think of yourself any less.
You may want to also check about doing something with your eggs before starting chemo if you have time. I wish you all the very best in this journey.
My thoughts and prayers with you
Sandy :)
