My wife converted to Tennessee fandom before she died in 2010, it was something that was special for us as well. And there are others here with spouses facing terrible illness (bigorangefish). And probably others who haven't spoken up.
We can support each other. Vols help Vols. If you, or anyone else is going through something like this, please reach out. Say something. Let us know if you need a little encouragement or support. There are people who understand what you're going through, and can be there through the dark times.
Just say the word.
