I feel you on the Christmas tradition! My family sets price caps on presents and I think it saves a lot of stress. Ever since I was 21 or so, the best part of Christmas was the food and the celebration, not the presents.

Sleep is so important and it’s great you’ve got a solution with a cpap machine now. Well done!

As for your techie child, it may be part of an ongoing trend in tech that things are getting worse instead of better - I feel that myself, and I know my friends do too - but they could also just be growing out of their hobbies and exploring new aspects of life. After working at a tech job I don’t want to spend my evenings at a computer any more, so I’ve started riding motorbikes and getting into photography, gardening and other outdoorsy stuff in the last few years.
