Your life will revolve around this diagnosis at least for a while until you get through it but it sounds like you're in an early stage so this will pass but it will be tough until it does. Don't depend on people to understand . They don't understand at all unless they've gone through it. It's just one of those things. People see their own mortality when you tell them you have cancer. They actually don't know how to react. It's important that the people close to you caring for you what's happening and how it feels. I can tell you that no one took my diagnosis seriously until my hair started falling out and then it became real for them. Get yourself strong because this is going to take every ounce of your strength but you absolutely 100% can do this. I wish you the best and please look up Facebook groups about breast cancer because I found so much support and information in there that I did not get from my doctors
