Finding Out I have cancer..

 just found out yesterday that I have breast cancer. I am feeling extremely depressed and all alone. My mom got diagnosed with breast cancer when she was 19, shortly after she had me. I am now 22 and finding out after discovering a lump about 4 months ago, I had been avoiding going because I was so scared, now I am even more scared. I just don't know what to do right now... I'm feeling very depressed and unsure if I even want to fight it right now. Its just a while lot to take in at the moment.... .
