I think for many there is an aspect in which, at some point during early childhood, they did experience good/joyous holidays with a loving family.

Unfortunately, for some, that does not continue into teenage years/young adulthood/the rest of life. For a variety of reasons.

Those memories & the potential yearning for them do not particularly go away for most, it seems to be part of the human condition. Methods of coping with the loss of meaningful holidays are vast, but substance abuse seems quite common.

While I do not know how universally true this is - I can only say I’ve heard many an anecdote being from a military family & I’m currently living on a marine base - it seems similar to soldiers fated to die gruesome deaths in foreign lands screaming for their mothers in their final moments. A somewhat universal experience. Maybe I’m thinking too deeply into it though.
