Stacie - your husband needs you to share his optimism and the joy he feels. Try to think of all the positives, enjoy the special moments you have to the fullest and celebrate! My son is 6+ years from the end of his Tx and the "what-ifs" still attack me sometimes but I quickly push them out of the way - it really does get easier. Being my son's CG has made me appreciate so much more the good things and the small things, too. No one knows what tomorrow brings but we cannot let it rob us of the happy experiences that are possible today. Oral Cancer has already done ENOUGH damage! - don't let it take away even a moment of pleasure that the two of you can share together. Meditative deep breathing is good, exercise or anything that gets oxygen to the brain, doing something for someone else, etc. Many years from now, when you are both "old and decrepit" your memories of the happy stuff will keep you going. So get started, "fake it 'til you make it" - You can DO it!
