I hope that you are both doing well. It is a hard thing to deal with. I had a brain tumor and treatment at Johns Hopkins in 2013. It was a Long 18 months but my wife was a great caregiver and always positive. I know now she was worried but I was just concerned about surviving and staying awake in the beginning. One day at a time and it is a good idea for a b day every week. I also had a number of friends stop by during radiation. Keep in touch with friends and family and lean on them as needed.
