@kdeey, we all understand here. That's why this online group is so great. You can ask anything and say anything. There's no judgement.
Good on you phoning the breast care nurse. They are amazing. The main thing is to reach out when you are overwhelmed and stressed. Who wouldn't feel stressed out when facing all this.
You daughters will get through ok. They will be stronger than you think. My son was about almost 30 when I was diagnosed and he was so amazing. He said he knew I'd get through because I never give up on anything. He came to chemo with me when he could. Some of my chemo was in lockdown so when that happened I had to go it alone. I shaved my head just as chemo started and he came to hair salon with me when I did that.
This is a bit of a roller-coaster ride and you still have the chemo to do so don't hesitate to reach out with any questions or concerns.
