If it works for you. I prefer lighter works that take my mind away from my problems instead of reminding me of them.

In that case you'd like W40K parodies such as "If the Emperor Had a Text To Speech Device" more than canon. That series helped act as at least one of my earliest introductions to 40K (I confess what really first got attention was seeing "Cultist-chan" artwork about a decade or so ago), and while I'm still very much a casual 40K enjoyer (meaning my lore knowledge is still limited) I have learned the big thing with 40K in general is "don't take it TOO seriously."
