Hi Cas,
first off she is lucky to have a friend like you to help her through this. Radiation and chemo are no picnic and it'll be tough sledding for a while. Most people ease into it though - it doesn't happen immediately. Keep a positive attitude - she will need a rock to stand on. If her husband doesn't go with her to Tx or to the doctors visits then go and be a scrupulous note taker. As treatment progresses she'll probably suffer from fatigue and maybe nausea as well. She will also not want to eat because of 2 reasons: first, the radiation does a number on the taste buds (they will fully recover) and secondly, radiation burns and nausea may make eating difficult. Try to stay on top of nutrition and water intake. It is wise to keep a log of medication, food and water consumed. Helping her out around the house and with the kids will be a wonderful gift if she accepts it. Most of us get pretty beat up from the treatment and we survive and get better. This is normal. You may want to consider finding a caregiver support group to talk out any fears or concerns. Bear in mind that she may be angry, sad, depressed, fearful, forgetful, fatigued, and maybe even abusive at times - don't take it personally -she doesn't mean it and will be eternally in your debt. We are always here for you also...
