Now that we know for sure that Mum's only got a few months left, if that, I find it very hard to listen to very emotional songs and do tend to change the channel very quickly. I tend to compartmentalise my feelings, it's the only way I could cope with all the things I've had to deal with with my daughter, I am using the same technique with Mum or else I'd get nothing done.
It probably means I come over as rather emotionless, but it's my coping strategy. Stoicism is the word, I guess. The only time I let it get to me I ended up driving the car into a wall! I fear losing it could happen if a song gets to me, and if I lose it I may not get it back.
Laughter helps too, my Mum jokes about death a lot, she's very humourous even now.
ETA: Apologies, that was rather off-topic but very cathartic
