Glad you found us. First, the onc needs to get your dad's pain under control. Is he taking any pain medication? As long as the pain is so bad, he can't think of anything else, and, of course, will be depressed. And, yes, it is normal to go in and out of depression with LC. My wife does this frequently, even when on an antidepressant. But your dad needs positive support and hope, and there is plenty around here. My wife was given 9 months, and she is 2 1/2 years from diagnosis. The prognosis in LC is all statistical, and each patient is an individual. Best to you all. Glad you have good support from your hubby and family. Let us know how to support you. Don
