hi -
I'm so sorry to hear about your mothers diagnoses. It is scary to hear the word "cancer" and not knowing what will happen. Please know that you are NOT alone – there are MANY people out there dealing with the same thing you are and feeling the same way you do. It is normal to cry a lot, it is normal not to want to see your mom knowing that all you feel like you are going to do is cry, it is normal not to know how to find the strength to support her.
Sometimes when something is just too difficult to get the words out without crying you can try writing the words. You can hand her a letter and stay there with her while she reads it. Maybe if you want to show her support in “small ways” you can do things around the house for her (cleaning dishes, putting things away, vacuuming, dusting, etc).
Most importantly I would encourage you to talk to someone -- friends, minister/rabbi, a support groups for teens. you can call the American cancer society 24/7 at 1-800-227-2345. also the University of Chicago hospital has a cancer resource center where you can find answers, talk to someone, find support - 1-877-824-0660 or http://www.uchospitals.edu/specialties/cancer/crc/
I hope all goes well for you and your family. Take care
