Yes keep the faith! I had Stage 3 - exactly like your daughter. Double mastectomy etc. I'm here and last week said no cancer - that makes it 3 yrs free. I went through it with flying colors. Well, let's say I went through it. My husband remembers some pretty bad days. I wasn't thrilled about the 3 'tattoos' I had to have to set up the radiation. But I'll take 3 pin dots over cancer any day.
Emotions were on the edge going through it and I could feel crying coming on with no real reason. So I'd say ok, I'm going to cry now, but it's nothing in particular. We would almost laugh while I was crying. Five minutes later, back to reading again. We laughed a lot at the absurdity of cancer. I think about it every day. I'm thrilled to be here. You are blessed with a daughter, and I know she'll make it through as I did.
