My day job is in hospice care. One of the ways it helps me cope is by reminding me that I'm not dying yet and that there's still a lot I can do to help others. (Take that, people calling me a burden! I ain't going anywhere yet!)
Done all that. I now have a CPAP to keep me breathing through the night. The only side effects of that (besides making a major project out of getting ready to sleep) is an imprint of the mask on my face.
