Hi Laura,
Welcome to this incredible support network online. I'm so sorry to hear about your beautiful Mum - I know all too well how this feels. Your Mum sounds amazing, and I'm so glad you also have the support of your Dad and lovely sister. A breast cancer diagnosis is just heart-breaking, and there will be a lot of hurdles in the journey ahead, but there will also be a lot of beautiful moments where you smile together, laugh together, and get through it together.
I know that right now everything must feel very frightening, but it does get easier as you fight it together. Your Mum sounds like a fighter! And the thing that will help her most is the love that you, your sister and your Dad have for her.
It's very natural to feel overwhelmed and scared. This website is a great place to come to share some of those fears. And anytime you want to talk, please let me know sweetie xxx
