Hello Molly, I'm so sorry for your diagnosis but glad you have joined this site. You will find so much experience and support here.
Everything you are feeling is completely normal - even though all our diagnosis and treatment are different, all the women on this site have experienced the disbelief of hearing they have cancer. You are not alone.
i know it seems impossible at the moment but you will feel a lot better once you see your surgeon and have an initial treatment plan.
There are so many wonderfully positive stories on this site too Molly. We have to count our blessings that we live in a country with excellent research and great success rates in treating cancer.
We all share and learn from each other so please feel free to ask questions or just vent. You will be amazed at your strength - we are all here for you Molly. Jane xx
